Mg-C Brick

Introduction

It is called high calcium magnesium brick. Magnesia refractories are mainly composed of calcite and three calcium silicate. It is composed of sintered brucite or fused magnesia and carbon material graphite as raw materials, with carbon-containing resin as binder, through mixing, molding and about 220 degrees Celsius heat treatment, from carbon to form a continuous network phase of periclase grain wrapping products.
