Breeding method: | Two methods, HPHT (ارتفاع ضغط ارتفاع درجة الحرارة) والأمراض القلبية الوعائية (ترسيب الأبخرة الكيميائية). |
raw material: | Diamond seed (seed) and carbon source (for CVD method). |
ضغط: | Generally between 50-70 kbar (HPHT method) أو 0.1-1 kbar (CVD method). |
temperature: | Generally between 1200-1500°C (HPHT method) or 700-1100°C (CVD method). |
time: | Usually ranging from a few hours to a few days. |
Metal catalyst: | Some CVD methods need to use, such as Ni, شارك, إلخ. |
Diamond Yield: | That is, the proportion of raw materials converted into diamonds, generally ranging from 0.1% إلى 50%. |
Diamond Quality: | The color, بحجم, impurity content, hardness and other indicators of diamonds can be controlled and adjusted through different cultivation conditions. |
