Tabular alumina, also known as alpha alumina, is a pure, sintered corundum that is completely burned and not added with any additives such as MgO and B2O3. It has a crystal structure of coarse and well-developed α-Al2O3, and the content of Al2O3 is above 99%. The table-like crystal structure, small pores, and closed pores make it a highly porous material with a rough equivalent porosity to fused corundum. It is characterized by high purity, good volume stability, minimal re-sintering shrinkage, and high-temperature treatment of refractory or castables used for production. It also has good thermal shock stability and bending strength.
The use of Tabular alumina in refractory materials is significant. It is widely used as a main component in aluminum carbon, aluminum-magnesium, magnesia-carbon, magnesium-spinus, aluminum-chromium refractory bricks, or as an enriched alumina component. It can be used in a variety of industries, including steel, casting, ceramics, and other fields. In the steel industry, it is used almost in all stages of ironmaking, foundry, and petrochemical processes.
The production process of Tabular alumina is simple and efficient. The raw materials are melted together, and then a solid-state reaction is induced at high temperature. The product is then cooled slowly and ground into the desired shape.
Tabular alumina has a high refractoriness, which makes it an excellent choice for high-temperature applications. It has excellent thermal shock resistance, creep resistance, and wear resistance, which makes it ideal for use in the production of refractory bricks and other high-temperature materials. Its unique crystal structure and porosity make it an ideal material for high-temperature processes in the steel industry.
In conclusion, Tabular alumina is a high-performance refractory material that has been widely used in various industries. Its high refractoriness, excellent thermal shock resistance, creep resistance, and wear resistance make it an ideal choice for high-temperature applications. With its simple production process and high-quality properties, it is a material that is sure to continue to be a valuable addition to the industrial landscape.
