Brown Fused Alumina,Brown Aluminium Oxide, Refractory Raw Materials

1. Brown Fused Alumina 95%
Product Code SC-B95
It is fused in an electric-arc furnace by high temperature. Its main raw materials are optimal bauxite anthracite. The micro hardness is 1800-2200kg/mm2. The degree of refractory is more than 1850. Be used to produce all kinds of corundum series ramming and gunning mixes, castables and common bricks.
Product Code SC-BT95
This kind of brown corundum is fused in a special ace furnace, named tilting furnace. Characterized by high purity, good crystallization, strong fluidity, low coefficient of linear expansion and good corrosion resistance, so the products have the higher toughness and better anti-impact ability, it is well used for produce high quality refractory products.
Product Code SC-BC95
950 degree centigrade calcined treatment with SC-B 95% grade, it releases all crystalline inside stress and potential reaction of impurity and brings an extremely stable property during sintering process, It is specifically used for applications such as bricks, tiles, filter plates, etc where spalling is an issue
