Alumina based Sintered Magnesium aluminium Spinel is made from high-quality alumina and high-quality magnesium oxide, adopting a unique technique and sintering at high temperature above 1900 C. It has the characteristics of strong corrosion resistance, good slag resistance, high thermal vibration stability and high temperature resistance. Compared with the current market products, it has higher strength and bulk density, lower porosity and water absorption, so it has better high temperature performance.
Magnesia-Alumina Spinel brick (HLMLJ), as chrome free produces , are specially developed for the transition zone of large scale dry-method cement kiln.
Application include but not limited to the transition zone in proof of EAF, basic oxygen furnace, steel ladle, cement rotary kilns glass tank regenerators and lime kilns.
Magnesium aluminum spinel brick with low porosity, high strength, good thermal shock stability, corrosion resistance and other excellent features, improve the life of rotary kiln lining.

Spinel Gemstone
Spinel crystallizes in the isometric system; common crystal forms are octahedra, usually twinned. It has an imperfect octahedral cleavage and a conchoidal fracture. Its hardness is 8, its specific gravity is 3.5â??4.1, and it is transparent to opaque with a vitreous to dull luster. It may be colorless, but is usually various shades of pink, rose, red, blue, green, yellow, brown, black, or (uncommon) violet.
