Product Introduction

Silica insulation 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.

Features

1. High refractoriness under load.

2. Energy-saving.

3. Less heat radiation loss.

4. Low thermal conductivity.

Application

Silica insulation 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.
