复合型传压介质的现状及发展

Actuality and development of complex pressure medium

对我国高压合成目前所用传压介质进行了较详细的概述,针对叶蜡石、白云石和氯化钠加添加剂(氧化镁或者氧化锆等)作为传压介质所具有的特征和性质分别进行了阐述和对比,详细介绍了用它们中的两种或两种以上的材料复合后,来承担起高压合成所需的传压、密封、绝缘以及保温等作用。并且经实验证明合成效果有很大的改善,从而降低了高压合成的成本,提高了合成的效率和质量,并给出了作者自己的观点和意见。

The paper carried some detailed summaries on the pressure medium used for diamond synthesis, such as pyrophyllite, dolomite and the sodium chloride （NaCl） with some additives （MgO or ZrO2 etc）, separately described and compared the properties of each of them, and introduced that using two kinds or more of them to work as complex pressure medium. Experiment demonstrates that the synthesis effect has been improved. By this means, the cost of the high pressure synthesis was cut down and the efficiency and the quality were enhanced, and more than that, some views and attitudes were given.
