宝石级金刚石培育技术评述

宝石级金刚石的培育技术比较有效的方法是美国GE公司首创的HPHT温差法.本文对宝石级金刚石的培育技术、发展历程、现状、影响培育宝石级金刚石晶体质量的生长速率、合成温度、掺杂等因素作了简要回顾和评述,找出了差距,为宝石级金刚石培育技术的研究指出了可借鉴的模式.宝石级金刚石培育技术经过近40年的不断完善,国外已实现了商业化生产,而我国还处于实验室阶段,显然差距是很大的.随着人们生活水平的不断提高和科学技术的发展,宝石级金刚石需求也在日益增长,引起了很多制造商的关注.

Statement on producing techniques of gem-grade diamond

The more efficient produce technology of gem-grade diamond is HPHT temperature difference method which was created by American GE Corporation. The article briefly reviews and states on the produce technology, developing process, present situation, growth rate which influences the crystal quality of gem-grade diamond, synthesis temperature, adulteration and other factors. It discovers the differences and provides a referential pattern for the research of gem-grade diamond. After nearly 40 years improving, abroad countries has carried out the commercial produced the gem-grade diamond, while our country is still in the laboratory. Obviously, the difference is remarkable. With the improving of living level and the developing of science technology, the demand for gem-grade diamond keeps raising and coursed more concern of manufacturers.
