White Silica Fume
Amorphous white silicon oxide powder is obtained by filtering the dust extracted from silicon metal production in an electric furnace. Silica Fume White has a high SiO2 content and very low impurity levels. Its use in refractory castables and High/ Very High performance concrete improve their mechanical properties and their durability. Its stability to temperatures of 1200ºC and its good sintering properties make it a raw material perfectly adapted for ceramics and refractory castables. Its white color enables its use in aesthetical and decorative civil engineering work.
