معامل وصف
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.
