Product Description

Product Description

Low Thermal Conductivity Light Weight Silica Brick Silica Insulation Brick
Product Introduction:
Light weight silica brick refers to a kind of refractory products made from silica as the main material and with SiO2 content not less than 91%.The main mineral composition of silica insulation brick is phosphorite and cristobalite.

Application:
Light weight silica brick has excellent fire resistance, with only small residual expansion, and good thermal stability. They are suitable for industrial furnaces such as coke ovens, hot blast furnaces, glass furnaces, and carbon furnaces.

Features:

1.High refractoriness under load. 
2.Energy-saving. 
3.Less heat radiation loss. 
4.Low thermal conductivity.
