Silica bricks are the main species of silica-based refractories, where the mass fraction of sio2 is not less than 93%. Silica brick is a typical acid refractory bricks, the acid slag has a good resistance to al2o3, feo, fe2o3 and other oxides also has good resistance, but the resistance to alkaline slag is poor, easy to cao, k2o, na2o and other oxides and damage. Silicone brick softening temperature as high as l640-1680 â??, long-term use at high temperatures more stable. But the thermal resistance of silicon brick is poor, refractoriness is not high enough.

Corundum brick (sintered corundum brick) with dense alumina clinker as raw material made of corundum brick. The brick has a high melting point, stable performance at high temperatures, room temperature and high temperature mechanical strength and wear resistance is good. Anti-metal erosion and anti-oxidation, superior performance.
