glass furnace used high quality refractory silica brick

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 ℃, long-term use at high
temperatures more stable. But the thermal resistance of silicon brick is poor,
refractoriness is not high enough. The properties of silicon bricks include
chemical mineral composition, true density, bulk density, refractoriness, load
softening temperature, high temperature volumetric stability, thermal shock
resistance and slag resistance, etc., with the nature of raw materials, crystal
transition conditions and manufacturing process And many other factors are
closely related.
