从上海地区看硅尘开发利用发展前景在金属硅和硅合金生产过程中产生大量主要成分为ＳｉＯ２的粉尘，是无定形ＳｉＯ２微粒，我国和美国称硅，日本称活性硅。这种硅上质量轻，约比水泥轻１００倍，大部分粒径小于１．０微米，平均粒径为０．１微米，不易浸湿，比电阻大，且... From the view of the Shanghai area, the prospects for the development and utilization of silica dust in the production of metal silicon and silicon alloys produce a large amount of dust with a main component of SiO2, which is an amorphous SiO2 particle. China and the United States refer to silicon, and Japan refers to active silicon. This kind of silicon is light in weight, about 100 times lighter than cement, most of its size is less than 1.0 micron, its average particle size is 0.1 micron, it is not easy to wet, its specific resistance is large, and...
