晓婷编辑: 《前途无量的石英硅微粉》在贵刊1994年12期发表后,接到许多来自全国各地信件、电话,现在简复几个问题。 1.关于开发一个项目的基本条件 许多朋友信中说:“我们这里石英很好,很多急待开发”,“我们想搞这个项目”等等,这种要早日利用资源的心情是完全可以理解的,但是对矿产资源开发首先要搞清资源,例如说,当地有多少石英,其次要搞清SiO_2的品位是多少?搞石英微粉不同用途,SiO_2含量要求不一样,搞超纯粉,原料的SiO_2含量就应该在99.97％以
Xiaoting Editor: “Promising Quartz Silica Powder” After your magazine published its 12th issue in 1994, it received many letters and phone calls from all over the country. 1. Basic Conditions for Developing a Project Many of my friends said in a letter: “We are here quartz is very good, a lot of urgent development,” “we want to engage in this project” and so on. This kind of feeling of early use of resources is completely understandable For example, how many quartz is there in the world and what is the grade of SiO_2? There are different demands on the use of silica powder for different purposes, and the requirements of ultra-pure powder and raw materials SiO 2 content should be 99.97%
