Product Details

Magnesia-alumina brick

Mainly used for the regenerator checker of glass furnaces.

Magnesia-alumina brick is a chrome-free alkaline refractory manufactured using high-purity magnesia, fused magnesia and fused magnesia-alumina spinel as the main raw materials. It is produced by adding an appropriate amount of mineralizer to improve sintering properties and toughening agent to optimize microstructure, followed by high-pressure forming and high-temperature firing.

This product features excellent thermal shock resistance and strong resistance to alkaline slag corrosion.
