Magnesium Aluminate Spinel

The products are made from high quality raw materials. After

Product diagram

inspecting – crushing – homogenizing – powdering – bricking

– drying, then sintered at high temperature in the Tunnel Kiln.

They are highly consistent in quality, can be widely used in the

production of refractory products with high thermal shock

resistance and anti-corroding ability for metallurgy,

construction and glass industry.
