摘要
高温高压合成超硬材料需要密封介质,叶蜡石是目前国内使用最普遍的密封、传压、保温、绝缘材料。文章利用X射线技术、Raman光谱技术、电子显微镜观测等,测量了叶蜡石的一些相关性质,尤其是高温高压后的一些性质,得到了对生产实践有价值的信息。
Synthesizing superhard material at high temperature and high pressure needs the sealing medium. Pyrophyllite is the most common seal, pressure transfer and heat preser- vation, insulation material in domestic at present. In the paper, the properties of pyro- phyllite especially after high temperature and high pressure were measured by X-ray, Ra- man spectrum and electron microscope. As a result, the valuable information for the pro- duction was found.
