Title:
PREPARATION METHOD FOR HIGH CORROSION-RESISTANCE ALUMINUM OXIDE CERAMIC MEMBRANE SUPPORT
Document Type and Number:
WIPO Patent Application WO/2019/010892
Kind Code:
A1
Abstract:
A preparation method for a high corrosion-resistance aluminum oxide ceramic membrane support, comprising: drying an aluminum oxide support until the water content is less than 2 wt%, dumping at a low temperature of 1000-1200°C, and sintering the dumped aluminum oxide support at a high temperature of 1550-1700°C under vacuum and constant pressure atmosphere to obtain a product. According to the method, the acid and alkali resistance performance of the product is significantly improved, and the service life of a kiln furniture is prolonged; energy consumption is reduced, and the manufacturing cost is reduced by about 70%, and the method is an innovative process route for producing the aluminum oxide ceramic membrane support.
