Chemical analysis

High purity alumina powder is white micropowder with uniform particle size, easy dispersion, stable chemical performance, moderate high temperature shrinkage performance and good sintering performance; high conversion rate and low sodium content. High purity alumina is the basic raw material to produce heat resistance, wear resistance and corruption resistance products, such as high aluminum refractory materials, high strength ceramic products, automotive spark plugs, advanced abrasive materials, with high melting point, good thermal stability, large hardness, good wear resistance, high mechanical strength, good electrical insulation resistance, corrosion resistance, widely used for shaping, irregular refractory materials, refractory binder, abrasion wear resistance, high purity refractory fiber, special ceramics, electronic ceramics, structural ceramics, stainless steel, granite and other decorative materials mirror polishing. a alumina can meet the requirements of users of different uses and different process conditions by using Class I industrial aluminum oxide, aluminum hydroxide and additive technology after low-temperature phase calcination, and then adopt advanced grinding technology and technology to produce the active alumina micro powder, characterized by large activity and fine granularity. It is especially suitable for stereotyped products and refractory pouring materials, plastics, patching materials, spray additives, daub materials and other uncertain refractory materials, which plays a strong role on improving the high temperature strength of refractory materials and improving the corrosion resistance performance of materials.
