The Study Of The Technology Of Synthesizing Diamond In Powder Catalyst And Large Chamber And Its Application

It is two great evolvements that the technical of synthesizing diamond using powder catalyst and enlarging equipment. If hasn't a corresponding the technical of synthesizing diamond, The ultra-high pressure equipment hasn't vitality. The aim of enlarging equipment is enlarge the reaction vessels. Consequently, benefit to increasing economy. Secondly, The quality of product is enhanced or a new product is produced. On the basis of tutor's right guidance and the predecessor's studying, The following research work has been completed:1 .The import task is researching the technical of Φ 40mm synthesizing diamond using the equipment of Y-500. Based on the technical of synthesizing diamond, the paper has synthesized RVG and high quality diamond. This work has promoted advancement of the trade.2. Based on the analysis of the mechanism of catalyst, the author think that the fundamental of structure corresponding is lack of foundation.It shows that:1) Based on the analysis of theory and practice, the paper has advanced the development direction of the ultra-high pressure equipment in my country. That is to say, the ultra-high pressure equipment should series .and enlarge. At the same time, we must stand to the principle of 100Mpa in the course of designing and using. And the stability is the precondition.2) Based on the theory of the ultra-high pressure technology, the paper has designed and analyzed the configuration of the Y-500 equipment, and advanced it's dimension and the technical of synthesizing diamond.3) Based on the analysis of the content of impurity in diamond, the paper has advanced the choosing principle of the catalyst.4) Based on the analysis of impaction that the catalyzeres impact on synthesizing diamond, the paper has advanced a suit of perfect theory, and designed a kind of catalyst. The catalyst has good performances and good application foreground by repeat tests.5) The paper has researched the synthesize chamber, the synthesizing technical and the configuration of the chamber, And synthesized RVG. Especially, The RVG diamond has been synthesized successfully, it has filled up the blank in my country, it can provide a good kind for diamond exporting.6) The paper manufactured bits and saws using synthesized high quality diamond. And evaluated its performance in drilling application, obtaining better results.7) The fission saws have been synthesized. Because the saws decreases incision, improves the working condition of blade , the life of this saws is longer than others, the drilling speed is increased greatly. It shows that the saws have a broad foreground.
