Magnesium-aluminum spinel

- Jun 17, 2019-

Magnesium-aluminum spinel has good corrosion resistance and good thermal shock resistance. Its main application is as follows: First, instead of magnesia-chrome sand, magnesium-aluminum sharp stone brick is used in cement rotary kiln, which not only avoids chromium pollution, but also has Excellent resistance to spalling, and second, it is used to make ladle castables, which greatly improves the erosion resistance of ladle lining. Its application range is still expanding, such as magnesium-aluminum spinel products for non-ferrous metallurgy, glass industry and so on. Magnesium-aluminum spinel is a highly promising high-grade refractory raw material.

Spinel is a mineral composed of magnesium aluminum oxide. It contains magnesium, iron, zinc, manganese and other elements and can be divided into many kinds, such as aluminum spinel, iron spinel, zinc spinel, manganese spinel. , chrome spinel, etc. Different spinels can have different colors due to different elements.
