99.2 content tabular alumina sintered corundum flake alumina 0.5-1mm 1-3mm
Tabular alumina is a completely recrystallized -al2o3, which is sintered at a temperature slightly lower than the melting point of imported alumina after batching, grinding, and molding. The crystals are arranged staggered in a list, which increases the mechanical strength of the particles. Closed pores are mainly evenly distributed inside and between particles, with high bulk density, low apparent porosity and low water absorption, which reduces the amount of liquid used in reprocessed products

| Tabular alumina use | Tabular alumina is an ideal refractory material. It can be used as an aggregate in various aluminum refractory materials, and can also be added to other aluminum unshaped refractory materials. It can be widely used in steel, casting, ceramics and other industries. , and its application in the iron and steel industry almost covers the whole process of iron and steel making. Applications in the steel industry 1. Sliding nozzle 2. Ladle castable 3. Prefab | ||||||
