Preparation method of aluminum oxide ceramic material with micron-size porosity
The invention relates to a preparation method of an aluminum oxide ceramic material with micron-size porosity. The ceramic material is formed by sintering aluminum oxide powder and sintering aids which serve as raw materials, wherein the sintering aids are prepared by compounding calcium, copper and titanium. According to the preparation method of the aluminum oxide ceramic material with the micron-size porosity, the suitable sintering aids are selected; the sintering temperature of the aluminum oxide porous ceramic is reduced under the condition that the special performance requirements of resistance to chemical corrosion and resistance to erosion can be met, so that the purposes of reducing the production cost, expanding the aluminum oxide pores and especially expanding the range of application of ceramic separation membranes are achieved; the prepared aluminum oxide porous ceramic material is high in strength and high in resistance to corrosion.
