This text contrapose on the contradiction between price of alumina powder material and performance of alumina ceramic manufacture at present. Abundant natural bauxite mineral in China as main raw materials was used through the favorable craft course and a small amount of other auxiliary additive to produce grinding medium which have the character of color white, higher performances, lower sintered temperature, fewer consume of resources, cheaper production cost, etc. And the problem of producing high-level grinding medium only using expensive industrial alumina powder was solved and pollution in production of alumina powder was avoided. So the environmental pollution and energy consuming can be reduced and high added value of bauxite can be achieved through this method. The experimental design continued to use the industrial production route and apt to realize industrialization, once it is put into production, enormous social effect will be achieved.
