The
SiO n the micro-silica is an amorphous material so that micro-silica is a small particle with high activity, large specific surface area, and favorable physical and chemical property.
The daily production of silicon metal is 50t. The standards of silicon metal
are different from country to country, such as ASTMA922 in the United States;
JISG2312 in Japan; DIN17560 in Germany; 2169 in Russia and
GB2881 in China. Our products are also known as 441 and 553.
