Spinel
Bauxite-based Sintered MgO-AL2O3, Spinel
It is sintered over 1800℃ in unique technology with high quality bauxite and magnesium oxide as raw material. It is well know for anti-erosion,corrosion resistance, anti-strip, good slag resistance, high thermal shock resistance, high temperature resistance and etc… Compared with other spinel in the market, it is higher in strength and bulk density and lower in porosity and water absorption. So that it has better temperature performance and is ideal material for refractory products such as Magnesium aluminum spinel bricks, ladle bricks and ladle castable which are used for rotary kilns of cement and lime.
