High pressure water atomization process of producing diamond catalyst powder

Since Mn content is high, brittle, rolling thickness is reduced to 0.4mm or less often brittle, limiting further thinning the thickness of the catalyst, and the long production process, energy consumption, material utilization is not high. Flake catalyst composition segregation was not conducive to the growth of high-quality diamond. [2] Since the late 1970s China has used elemental cutting tools, turning Fenxie and water atomized powder, in a continuing study of synthetic diamond powder catalyst technology, but there has been no major breakthrough, the main problem is not the quality of the powder catalyst high, such as the current number of produced water atomized alloy powder catalysts business, subject to restrictions on the production process, the oxygen content of up to 2000ppm. Water atomized catalyst alloy powder production is a systematic project, which contains two aspects of hardware and software, in general, the diamond producers for the production of metal powder atomization know polycrystalline diamond technology, so the investments are concerned most are in the hardware part, the result is to spend a lot of money to get things that are not ideal.
Catalytic iron-based alloy powder material by the main melting temperature, high pressure water spray crushing, vacuum drying is made. With its synthetic diamond crystal is good, golden color. Synthetic abrasive grinding catalyst results showed that: synthesis yields can be improved, reducing the carbide and raw material consumption, reducing the cost of production of diamond, while both high abrasive grade synthetic diamond, but also high-quality synthetic coarse particles and high-grade diamond. Synthetic diamond powder catalyst to octahedral crystal with six-based, high integrity crystal, the crystal is more pure, more than the total inclusions, more even distribution of the dispersed, with good impact strength at room temperature and high temperature.
