Core Technologies

Experienced professionals, state-of-the-art research and testing facilities and cooperative study enable Alfa Chemistry to master a wide range of core technologies, to name just a few.

  • Ultra-high temperature and high pressure synthesis: The synthesis of synthetic diamond and CBN is an extremely complex process that needs to be carried out under ultra-high temperature and high pressure. To achieve the synthesis of high-quality products under ultra-high temperature and pressure, Alfa Chemistry has made continuous improvements in the raw and auxiliary materials selection, synthesis process optimization, synthesis equipment improvement and control. At present, we have realized and mastered the high-pressure high-temperature preparation of various types of diamond and CBN.
  • Micropowder production process control: Ultrafine and high-strength diamond micropowder and CBN micropowder are important part in our business. Particle size, shape, strength and purity are the several key characteristics that affect the quality of micropowder. However, these core technologies have been fully mastered by us and a brief introduction is as follows. To overcome the inaccurate measurement problem of irregular and long particles, Alfa Chemistry adopts a dual detection method combining laser particle size analyzer and microscope inspection to test large particles and long particles, which has a good effect on the size distribution of micro-powder and the control of large and long particles. The strength of the micropowder is mainly controlled by controlling the strength of the raw material which is judged by the TI and TTI values. The purity of micropowder is controlled by selecting high purity raw materials, pretreatment of raw materials, purification of crushing materials and etc.
