Silica Fume
Silica fume, also known as microsilica, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica.
It’s widely used in refractory materials, including low cement castables (LCC), ultra-low cement castables (ULCC) and no cement (NC) castables. It can minimum the water addition, improve high temperature and mechanical resistance for cast refractories.
