活性碳、碳黑、石墨与金刚石晶种的生长

Active carbon,black carbon,graphite and diamond seed growth

介绍了活性碳、碳黑与石墨在过剩压驱动下金刚石晶种的生长．对两种无定形碳以及石墨在触媒中的分散溶解输运与再结晶进行了观察，对活性碳、碳黑在金刚石晶种生长中的机理作了探索性的讨论．三种碳片上的晶种均有明显长大。

Diamond seed growth by put on active carbon,black carbon and graphite under force of excoss pressure is deseripted.The dispersion,melting,transportation and recrystallization of two kinds of amorphous carbon and graphite in metal flux are obsevated.The mechanism of active carbon and black carbon in diamond seed growth is also be explorly discussed.Each of the diamond seeds on the three pieses of carbon expands obviously.Amorphous carbon is available to be used as the carbon origin of diamond seed growth.
