Enlarged Scale Tests on Diamond Synthesis by Pressure Transmitting and Sealing Medium with Inside Diameter of 42 mm and Composed of Kaolinite and Dolomite

  • 摘要: 高岭石具有良好的流动密封、固体传压及机械加工等物理性能,是传统传压密封介质原料叶蜡石的替代品。采用比纯高岭石更适合作为传压密封介质原料的某地高岭石矿物,经过配料、混料、装模、压制成型以及焙烧等工序,制成了高岭石-白云石质传压密封介质,并对其进行金刚石合成扩大试验。试验结果表明:高岭石-白云石质传压密封介质能够达到与叶蜡石质传压密封介质相当的效果;合成金刚石的单产为19 g,抗压强度不小于160 N的晶粒占32%,晶粒尺寸大于或等于0.30 mm的占82%,合成1 g金刚石的顶锤消耗小于0.5 g,合成过程稳定。
