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.

Silica bricks with SiO2 content of 93% or higher are acid-resistant refractory products widely used in coke ovens, glass melting furnaces, and iron & steel industry applications. These refractories offer excellent volume stability at high temperatures and strong resistance to acid slag corrosion, making them essential for arch structures and high-temperature zones in industrial kilns. Export-grade silica bricks are typically packed in wooden pallets with waterproof wrapping and meet international standards for global refractory material trade.
