江苏省东海县积极开发本地丰富的硅资源 ,初步建成硅微粉、石英玻璃原料、石英拉管等三个国家级优质硅材料生产基地。东海县石英储量达 3亿吨 ,居全国首位。近年来 ,相继开发了滤紫外线石英玻璃管、大口径透明石英玻璃管、低腐蚀密度压电石英晶体一大批高科技产品。目前全县硅 Donghai County, Jiangsu Province, actively develop the rich local resources of silicon, the initial building of silica fume, quartz glass raw materials, quartz tube and other three state-level high-quality silicon material production base. Donghai County quartz reserves of 300 million tons, ranking first in the country. In recent years, have developed a large number of UV quartz glass tube, large diameter transparent quartz glass tube, low corrosion density piezoelectric quartz crystal a large number of high-tech products. The current county silicon
