Magnesia alumina spinel brick

Introduction

Magnesia alumina spinel brick improves the thermal stability of magnesia bricks after adding alumina in its raw material. Magnesia alumina spinel brick uses low calcium content of high quality magnesia sand and industrial alumina powder as the main raw material.

Features

1. Good thermal stability
       2. Good anti-peeling performance
       3. Good heat resistance
       4. Anti-quenching and emergency hot
       5. Good corrosion resistance
