Magnesia Brick

Magnesia brick is an alkaline refractory material with magnesia content above 90% and periclase as the main crystal phase.Generally, magnesia brick can be divided into two categories: sintered magnesia bricks (also known as fired magnesia bricks) and chemically bonded magnesia bricks (also known as unfired magnesia bricks). Magnesia bricks with high purity and high firing temperature are called direct bonded magnesia bricks; bricks made of fused magnesia as raw materials are called fused combined magnesia bricks.

Characteristics:
1.Excellent slag resistance,.
2.High refractoriness.
3.Good thermal stability.
4.High cold crushing strength.

Application:
Magnesia brick is characterized by high refractoriness, good alkali resistance and superior refractoriness under load, and it is mainly applied to the regenerators of glass kilns and other high temperature furnaces.
