Magnesia Alumina Bricks

Magnesia alumina brick is an alkaline refractory product with periclase as the main crystal phase and magnesia alumina spinel as the matrix. Its alumina content is 5%-10%, which has good thermal shock resistance. According to Rongsheng Refractory Bricks Manufacturer, In order to improve the thermal shock resistance of magnesia bricks, alumina or special-grade high alumina

Silica Bricks for Sale

Refractory bricks with SiO2 content above 93% are called silica bricks. It is made of quartz stone as raw material, after crushing, adding an appropriate amount of binder, mineralizer, and part of siliceous clinker, after mixing, forming and drying, it is calcined in a kiln at 1400-1430℃.

High alumina brick is a kind of aluminum silicate refractory brick with alumina content above 48%. High alumina bricks are mainly made of high alumina bauxite as refractory materials, and other powders and binders are added. After mixing, it enters into the brick making machine to be pressed into shape. After being dried, it is

What is High Temperature Alumina Refractory Brick?

At room temperature, the thermal conductivity of aluminum oxide is half that of aluminum metal, which decreases with increasing temperature. The thermal shock resistance of Alumina Refractory Brick depends on its microstructure and the shape and size of the product. Generally speaking, its thermal shock resistance is moderate. In short, alumina has the characteristics of

Influencing Factors of True Density of Silica Brick
