Tabular Alumina Al2O3 Description
Tabular alumina Al2O3 is a pure sintered corundum that shrinks completely without adding any additives such as MgO, B2O3, etc. It has a coarse and well-developed α-Al2O3 crystal structure, and the Al2O3 content is more than 99%.
It has a plate-like crystal structure, small pores and many closed pores, and its porosity is roughly the same as that of fused corundum. It has high purity, good volume stability, and very small refire shrinkage. It is used to produce refractory materials or castables after high-temperature treatment. It has good thermal shock stability and flexural strength, but the price is higher than other alumina.

Tabular alumina Al2O3 can be used as the main component in aluminum carbon, aluminum-magnesium carbon, magnesia-aluminum carbon, magnesium spinel, and aluminum-chromium refractory bricks, or as a rich alumina component introduced into high-aluminum refractory bricks. Shaped refractory materials can be widely used in steel, casting, ceramics and other industries. The application in the steel industry covers almost the entire process of iron and steelmaking. Current application status of refractory materials made from tabular corundum in the steel industry.
After plate-shaped corundum is dried at 110 degrees Celsius and then heat treated, the density and volume will first increase and then slowly decrease. The density and volume obtained by heat treatment are not very different. The linear shrinkage rate is initially increased, but as the initial temperature increases, this shrinkage rate will decrease again.
This state is due to: at a set high temperature, kyanite is decomposed into a molten form; at the same time, mullite and free silica are also generated, and the initial volume becomes larger. As the temperature rises, the linear shrinkage rate is reduced. After high temperature, tabular corundum is more easily sintered.
