white tabular alumina 0-1mm,1-3mm,3-5mm refractory used tabular alumina
1, A kind of pure sintered corundum,without adding any additive
2, α- Al2O3 crystal structure,with more closed porosity
3,High purity, good stability volume density ,
4,Characterized by good heating volume temperature performance and good thermal shock resistance.
5. Replace fused alumina and white fused alumina in some application position and improve the performance of refractory material.
