SM6133 Silica Insulation Brick
Silica Insulation Brick Overview
Silica Insulation Brick is a lightweight refractory brick primarily composed of silica (SiO₂). Designed for high-temperature environments such as furnaces, kilns, and ovens, these bricks provide excellent thermal insulation. They are characterized by low thermal conductivity, high temperature resistance, and good thermal shock resistance, making them ideal for applications requiring both effective insulation and heat stability.
