Densified Silica Fume For Refractory

We are offering densified silica fume for refractory. Microsilica , also known as silica fume, is a byproduct of producing silicon metal or ferrosilicon alloys. Microsilica consists primarily of amorphous (non-crystalline) silicon dioxide (sio2). The individual particles are extremely small, approximately 1100th the size of an average cement particle. Because of its fine particles, large surface area, and the high sio2 content, silica fume is a very reactive pozzolan when used in concrete.
