Magnesia Carbon Brick
This product uses electro-fused magnesite and natural high purity graphite as feed materials and high quality phenol as a binder, which then goes through high speed blending, evacuated high pressure shaping, heat-treating, and other processes. It features a dense matrix structure, reasonable phase distribution, good properties of anti-spalling, anti-corrosion, high temperature volume stability, and heat conductivity.
