What is the application and preparation of high-purity alumina?

High-purity alumina is non-toxic and odorless. It looks like a fluid white powder and has excellent properties such as high melting point, high hardness, high resistance, good mechanical properties, wear resistance, corrosion resistance, insulation and heat resistance.

High-purity alumina is currently used as one of the cutting-edge materials in many fields such as optics, chemical industry, and special ceramics to manufacture translucent alumina sintered bodies, high-density particle sintered bodies, gem single crystals, artificial crystals, and electronic components, cutting tools, abrasive materials, luminescent materials, additives for special glass, plastic and rubber fillers, etc.

Since powder performance directly affects the final use effect of the powder, and powder performance is closely related to its preparation method, research on new preparation principles, preparation methods and production equipment is an important research and development task in the future.

As an emerging high-tech product, ultra-high-purity alumina powder with a purity higher than 99.9% has broad application prospects in domestic and foreign markets, and the demand is increasing year by year. The application of high-tech equipment has also become a trend in the production of high-purity alumina.

Traditionally active high-purity aluminum powder uses ball mills to prepare high-purity ultra-fine alumina. However, the high energy consumption and high investment cost of ball mills are well-known facts in the industry. It is obviously unwise to use such equipment to produce high-purity ultra-fine alumina.
