炸药——纳米结构金刚石的制备能源分析

ANALYSIS ON DYNAMITE THE PREPARATION ENERGY OF NANOMETER STRUCTURE DIAMOND

提起用爆炸的方法来制备纳米结构的金刚石,首先使我们想到就是炸药,因为炸药是产生高压高温的基源。炸药的种类很多,文章只对制备纳米金刚石的有关炸药——TNT和RDX的特性及其在爆炸过程中所显示的作用,以及它在爆炸中各影响的特点等问题做扼要描述。上述问题对长期从事静态高压高温合成金刚石或已涉足或将要介入这一技术领域的科技工作者可以说是陌生的,笔者通过近几年的调研和实践,深深体会到要想做好这一门新技术,并有所作为,对上述基本知识的了解是非常必要的。

Dynamite will occur to our mind when the exploding method for preparing nanometer structure diamond is mentioned since high temperature and high pressure is basically caused by dynamite. As there are so many kinds of dynamite the paper only briefly describes TNT and RDX that is related with the preparation of nanometer diamond and their function showing in the process of explosion and the characteristics of influencing factors when they are exploding. According to the authors experiences in the research on the technology it is necessary to know the above basic knowledge if the experts who know diamond synthesizing under static high temperature and high pressure conditions for a long time and now have involved in or about to participate in the technological field but not familiar with it.
