Fused α-β corundum brick characteristics

2023-11-07 Notre blog

Fused α-β corundum brick is an alumina-based refractory material made by melting and casting high-purity alumina raw materials at temperatures above 2000°C. Due to the different Na2o content, the composition ratio of a-Al2o3 and aluminum chemicals is different, so the products are specifically divided into three categories: a-Al2o3, a-BAl2o3, et…
