In terms of particle size, silicon micropowder is processed from natural quartz. The particle size is relatively large, including 200 mesh, 300 mesh, 400 mesh, 500 mesh, 600 mesh, 800 mesh, 1000 mesh, 1250 mesh, 3000 mesh, 5000 mesh, 10000 mesh is a kind of powder state. The fineness of micro-silica powder is less than 1 μm, accounting for more than 80%, and the average particle size is 0.1-0.3 μm, which is a kind of gray state.
Uses of Microsilica Fume:
1. Cement or concrete admixture
2. Refractory additives
3. Metallurgical pellet binder
4. Dispersant for chemical products
