We can provide the silica fume with the content of SiO2 90%--97%. Normally, silica fume suitable for the refractory castable production contain SiO2 more than 88%.
Silica fume is a byproduct in the reduction of high-purity quartz with coke in electric arc furnaces in the production of silicon and ferrosilicon alloys.
Silica fume is also named the Micro silica, which can be sued in the refractory castable to reduce the loss of adhesion rebound.
Silica fume in refractory pouring liquid could reduce water usage to improve fire resistance and improve production efficiency.
Silica fume is a very effective ash material, it is easy to coming into contact with mullite phase, provided that the presence of Al2O3 to improve high-temperature strength and thermal shock resistance.
