The data of cup of pottery and porcelain that the summary studied to 5 kinds differ: Xie Lashi, dolomite, magnesian, alumina, be based on dolomite composite material; The composition of material of cup of different to 5 kinds pottery and porcelain, function undertakes contrast; Use them to synthesize diamond at the same time, right the Ti that synthesizes diamond, TTi and other performance are comparative, conclude: The target such as the brilliant form that is based on cup of pottery and porcelain of dolomite composite material to synthesize a diamond, color, intensity is apparent excel other a few kinds of material. Accordingly, producing a large number of medium adoption actually to be based on cup of pottery and porcelain of dolomite composite material. Diamond of material of cup of keyword pottery and porcelain synthesizes Influence Of Ceramic Cup Material On Diamond SynthesisAbstract Five Kinds Of Different Ceramic Cup Materials, ie, pyrophyllite, dolomite, magne, Sia, aluminum Oxide, dolomite Compound Materials Were Studied And Compared And Also Used To Synthesize Diamonds. After Testing Ti, TTi And Other Properties Of Synthesized Diamonds, we Found Out That Their Color, strength And Etc. Were Much Better Than Other Materials With The Ce, Ramie Cup Materials Based On The Dolomite Synthesizing Diamonds. Therefore, the Ceramic Cupmaterials Based On Dolomite Are Widely Used In The Actual Production. Synthesis of diamond of industry of China of introduction of Key Words Ceramic Cup Material Diamond Synthesis 1 passes development of 45 years, obtained tremendous progress, so far, the diamond function of medium granuality and foreign diamond are basic and same, home of thick grain diamond also already preparation comes out, but function and foreign diamond still have certain difference. A shape accelerant that diamond synthesizes raw material to pass about 40 years piece application, will nearly 5 years had been replaced by place of pulverous accelerant technology stage by stage. At present the enterprise of 95 ％ above uses domestic diamond trade the diamond that pulverous accelerant technology synthesizes high grade. Synthesize the granuality grade of diamond to improve pulverous accelerant technology ceaselessly, come nearly two years, the method that the method that pulverous accelerant heats directly is heated secondhand gradually is replaced. Heat secondhand synthetic diamond technology is opposite at the tradition heat directly technology of methodological synthesis diamond has the following big clear advantage: ① heats secondhand 1/3 what methodological synthesis electric current heats directly only, bigger managing charge of electricity. ② heats secondhand scope of application of raw material of diamond of the synthesis in the method is wide, heat secondhand the scale of powder of the accelerant in synthesizing column can arrive from 30 ％ commonly 70 ％ . Heat directly scale of powder of the accelerant in synthesizing column can be controlled in 30 ％ only, if catalyst proportion is high, when heating directly because synthetic electric current is too tall, synthetic craft is not stable, do not have method control. ③ heats secondhand when the method can raise synthesis substantially, ask, and the hammer of hard alloy top that synthesizes diamond is used up inferior. Synthesize the extension of time at the same time, be helpful for diamond of high grade thick grain (40 granuality of 35 ／ above) grow. Anyhow, heat secondhand the necessary evolution way that the method already made pulverous accelerant synthesize a technology. Increase of demand of diamond of thick to high grade grain ceaselessly as domestic tool industry, heat secondhand the method is sure to obtain larger space in the application in synthesizing diamond and research. But at present home about heating secondhand the preparation function of the data of the most crucial cup of pottery and porcelain that uses in the method does not have research, affected greatly heat secondhand the methodological promotion application in synthesizing diamond. Material of cup of pottery and porcelain affects the craft that synthesizes diamond and the quality that synthesize diamond greatly. Article labor material of 5 kinds of different cup of pottery and porcelain. Study the result makes clear, material of cup of pottery and porcelain affects parameter of synthetic diamond craft not only, and the crop that also affects synthetic diamond greatly, quality, color. The experiment of diamond of synthesis of material of cup of 2 different pottery and porcelain is designed 2. This experiment uses preparation of cup of 1 pottery and porcelain cup of pottery and porcelain of preparation of 5 kinds of material, it is Xie Lashi respectively (area of channel of Beijing door head produces) , dolomite (region of Beijing room country produces) , alumina (99 ％ aluminous) , electric frit is magnesian, be based on dolomite composite material. Afore-mentioned material courses are broken and abrade to 120 eye with fine, join coequal proportional additive to mix even, it is Qb44mm × through heating up inject method to shape ' 4M2mm × 16. System of 5mm(h) cup state, and be in 900t2 agglomeration 4 hours, shape to be synthesized with Yu Jingang stone. 2. Equipment of high pressure of diamond of synthesis of experiment of 2 diamond synthesis is type of hinge of 6 × 25MN 6 tops hydraulic press, synthesis reacts if the graph is shown 1 times,housing assembles a form. The J35 that synthesizes column to be preparation of the science and technology that install peaceful among them, 40M synthesis column, dimension is Bin 1. 5mm × 15. 5mm, basically use at synthesizing 35 ／ the 40 high grade diamond that give priority to size peak value. Diamond synthesizes craft to if the graph shows craft curve 2 times,be used. On synthesis the requirement has the following at 2 o'clock: ① synthesizes diamond brilliant the largest proportion to be 68 body. ② uses same synthetic time, heat time is 40min.

Because change,can produce apparent bulk systole, meeting influence synthesizes pressure. A few kinds of material do not have other to change, contract without bulk. But differ as a result of what heat up coefficient of expansion and hot conductivity, the can greater pressure that affects synthetic craft and temperature. And affect the quality to synthetic diamond finally. 3. The impact of data of cup of 2 pottery and porcelain to synthetic craft parameter by the watch 3 can see, when synthesis differ as a result of what use data of cup of pottery and porcelain, caused synthetic pressure and the wave motion that synthesize electric current. Shi You of foliaceous dried meat causes larger volume to contract at changing when synthesis, complex pressure is highest. The others because a few kinds of material did not change to contract with bulk when high temperature high pressure, synthetic pressure is inferior. Because have relatively appropriate hot conductivity,be based on dolomite composite material at the same time, synthetic electric current is inferior. 3. Material of cup of 3 pottery and porcelain and the material of cup of relation pottery and porcelain that synthesize diamond Ti, Rnli are influential to synthesizing craft outside, mainer is bigger to synthesizing the quality of diamond to have impact, watch 4 be opposite for material of cup of pottery and porcelain the influence of the function that synthesizes diamond.

2normal >40normal >25 from the watch 4 in can see, the composite material that is based on dolomite compounds the effect of diamond, no matter crop quality is better accord with production to ask. Main reason was avoiding Xie Lashi material to change in the photograph in synthesis at composite material phenomenon, volatile makes an appearance. Generated volatile, be like water, the gas influence after entering synthetic housing undertakes to complex, foreign matter element enters diamond crystal easily, affect diamond quality thereby. Composite material is integrated at the same time the characteristic of the material of pottery and porcelain such as dolomite, magnesian, zirconia, there is the generation of volatile already when synthesis, have appropriate hot coefficient of expansion, hot conductivity again. Diamond grows below more stable temperature pressure field, those who add is magnesian, the powder of pottery and porcelain such as zirconia is advantageous to synthesizing diamond, so synthetic diamond has better integral performance. Afore-mentioned Ti, the measurement of 1Tri uses CMC, Il exceed hard abrasive to pound test meter; The measurement of magnetic susceptibility uses JCC, analyzer of B diamond magnetic susceptibility; Quiet intensity of pressure is spent use exceed detector of hard abrasive intensity. 3. Of the material of cup of influence pottery and porcelain that material of cup of 4 pottery and porcelain spends fully to synthesizing diamond color different, same meeting evaluates index to have major effect to the exterior of diamond, the color that affects diamond, spend fully, and affect the integrality to the crystal appearance that synthesizes diamond. Watch 5 in because Xie Lashi is in,synthesize from time to tome volatile, style of the wrap up in diamond is so more, color hair is green, nigrescent more. Be based on the composite material of dolomite, without volatile, the growth that is diamond again provided suitable space, the color of diamond, spend fully optimal. Express material of cup of 5 pottery and porcelain to be opposite synthetic diamond color, the contrast that spends fully can bigger impact goes to material of cup of pottery and porcelain of different composition of 4 conclusion ① complex craft parameter. The affects diamond particle size distribution with can older stuff of cup of pottery and porcelain of ② different composition, color is spent fully and the grade of diamond. The material that ③ should choose to have less volatile as far as possible regards cup of pottery and porcelain as material, volatile can cause very big effect to the function of diamond. ④ should consider the hot coefficient of expansion of material of cup of pottery and porcelain and hot conductivity integratedly, choose material of cup of compound pottery and porcelain.
