Silica Fume

Our silica fume is produced in global main ferroalloy manufacturing area, that is in the east of Helan mountain crossed by Ningxia and Inner Mongolia province located in northwest of China, where is surrounded by high energy consuming industry chain. Because of high grade silica with less impurity as well as abundant coal and electricity, it has large production of ferro-silica and metallic silicon. And gathered silica fume is in steady quality and adequate supply.

 

According to grade of SiO2 , the silica fume is divided to 7 levels: Grade 85, Grade 88, Grade 90, Grade 92, Grade 94, Grade 95.
