| titleOfInvention | A kind of colorless diamond synthesis preparation method of raw material stem |
| abstract | The present invention relates to a kind of preparation methods of colorless diamond synthesis raw material stem comprising following steps: 1) with water atomization prepares alloyed powder I and alloyed powder II；2) diamond seeds particle and zirconia particles are mixed and obtains non-metal powder III；3) alloyed powder I and non-metal powder III are mixed and is granulated and obtain alloyed powder IV；4) alloyed powder II and graphite powder are mixed and is granulated and obtain alloyed powder V；5) alloyed powder IV and alloyed powder V are mixed and compression moulding obtains raw material stem；6) purification process is carried out to get colorless diamond synthesis raw material stem to raw material stem.This method is added or is added without diamond crystal seed, is combined element absorption colour developing element by force using with colour developing elements such as nitrogen, creates the process conditions for eliminating the element that develops the color in diamond finished product, be a kind of efficient process of artificial synthesized colorless diamond. |
