Sintered Magnesia Alumina Spinel

Sintered magnesia alumina spinel is made with imported industrial alumina and dead-burned magnesia as raw materials, through multi-stage homogenization process, and sintered at ultra high temperature in shaft kiln. The product has high bulk density, more content of spinel phases, good crystal growth, uniform structure, consistent properties, so as to have good resistance to erosion, to spalling, to slag, to thermal shock and to high temperature. 

High quality synthetic magnesium aluminate spinel can be used as a new raw material for the manufacturing of shaped and unshaped refractory products, for example, for the application in magnesium aluminate spinel bricks for cement rotary kiln, bricks for ladle lining, castatles for ladle, which has been widely used in iron and steel metallurgy, cement rotary kilns and glass furnaces.

The brand names of JMA-50, JMA-66, JMA-78 and JMA-90 etc are available according to alumina content.

Available sizes from 15mm to 3㎛.

25kg/bag,1000kg/bag or other specific packing according to user’s requirements.
