Application of white corundum powder in refractories

In the abrasive industry, white corundum abrasives are often used. The particle size of micro powder abrasives is relatively uniform and the texture is fine. For example, black silicon carbide powder, green silicon carbide powder and white corundum powder are widely used in the industry. What are the applications of white corundum powder in refractory materials?
1. White corundum powder is widely used in refractory industry. It plays an important role in the improvement of shaped and unshaped refractories. It fills in the pores of refractories, increases the bulk density, reduces the apparent porosity, and increases the strength obviously. It has strong activity. It forms colloidal particles in water. Adding appropriate amount of dispersant can enhance its fluidity To improve the performance of castable, it has strong hydrophilicity, can enhance the cohesion of refractory, at the same time, it can greatly improve the high temperature resistance and prolong the service life of refractory products.
2. White corundum powder is widely used in high-performance refractory castables and prefabricated parts, large iron channel materials and ladle materials, permeable bricks, daub materials, self flowing refractory castables and dry wet spraying, oxide bonded silicon carbide products, corundum mullite push plate, high-temperature wear-resistant materials and products, corundum and ceramic products. In addition, it is also widely used in cement, construction and building materials industries Expand the application.
