Chemical analysis of high purity alumina

The high-purity alumina powder is white micropowder with uniform particle size, easy to disperse, stable chemical properties, moderate high-temperature shrinkage performance, and good sintering performance; high conversion rate and low sodium content. This product is the basic raw material for the production of heat-resistant, wear-resistant, and corrosion-resistant products, such as high-aluminum refractory materials, high-strength ceramic products, automobile spark plugs, advanced abrasive materials and other products with reliable quality, high melting point, good thermal stability, high hardness, Good wear resistance, high mechanical strength, good electrical insulation, corrosion resistance, widely used in shaped, unshaped refractory materials, refractory castable binders, wear-resistant abrasives, high-purity refractory fibers, special ceramics, electronic ceramics, and structures Ceramic, stainless steel, granite and other decorative materials mirror polished. It can meet the requirements of users with different uses and different process conditions. Alumina is produced by using first-grade industrial alumina, aluminum hydroxide and additive technology after low-temperature phase inversion calcination, and then using advanced grinding technology and technology to produce activated alumina micropowder , Its characteristics are large activity and fine particle size. It is especially suitable for shaped products and unshaped refractory materials such as refractory castables, plastics, repair materials, gunning materials, smears, etc. It has a strong effect on improving the high temperature strength of refractory materials and improving the corrosion resistance of materials.
