mm的片状铁基触媒，在六面顶压机上高温高压合成金刚石单晶。

The results show that in the case of {1 0 0}, the morphology of crystal changes from lowtemperature sheet to hightemperature tower with increasing the synthesized temperature, whereas in the case of {1 1 1} the change trend is contrary to {1 0 0}. When {1 1 1} facet or {1 1 1} was used as the growth facet, the sheetlike crystal is more difficult to incorporated for the metal inclusion regardless of synthesized temperature. With NiMnCo metal as solvent, large highquality gemgrade diamonds can also grow on {1 1 1} facet with proper temperature gradient.

结果表明：随着合成温度的升高，用{1 0 0}面生长出的晶体形貌由低温片状逐渐过渡到高温塔状，而用{1 1 1}面生长出的晶体形貌变化趋势则相反；采用籽晶{1 0 0}面或{1 1 1}面生长晶体，无论合成温度高低，包裹体都不容易进入片状晶体内部；只要存在合适的温度梯度，NiMnCo触媒同样适合利用籽晶{1 1 1}面生长优质大尺寸宝石级金刚石（≥4 mm）。
