White Tabular Alumina

详情

White tabular alumina is a kind of Sintered Tabular Alumina, which is got by sintering the high-purity alumina, do not add any additives. It is a kind of shrinkage completely sintered corundum. It has a high refractoriness, excellent thermal shock resistance, creep resistance and spalling resistance.

Well-developed crystal structure of alpha-Al2O3 significantly improved creep resistance. During the production process, there does not add any additives, it make the STAR have a high purity, good volume stability and minimal ignition lost.
 
Applications:
STAR is widely used in making high-performance refractory products for the applications in iron and steel, foundry, petrochemical, ceramics, glass and other industries. It is a satisfied material for making slide gate nozzle, refractory carstables for ladles, and performed units.
