Raw materials for manufacturing magnesium carbon bricks

Magnesia carbon brick is an unburned carbon composite refractory material. It is made of magnesium oxide, an alkaline oxide with a high melting point (2800°C), and a high melting point carbon material. The material is difficult to be corroded by slag and has added Various non-oxide additives and carbon binders. As a composite refractory material, …
