Product Description

Silica Brick Description:

Silica brick is premium acidic refractory brick with SiO₂≥94%, made of high-purity quartzite. It features ultra-high refractoriness under load, excellent acid slag corrosion resistance and stable volume under long-term high-temperature service. Widely used for coke ovens, glass melting furnaces, hot blast stoves and acidic kiln vaults. Custom sizes & special shapes available, ISO certified factory direct supply.

Silica Brick Features:

(1)High refractoriness under load.
(2)High heat conductivity.
(3)Good thermal shock resistance.
(4)Solidity stable of capacity in high temperature.
