发明名称 Ceramic filter and process for making it.
摘要 <p>A process for manufacturing a ceramic filter having a given pore size required as a filter membrane and also having superior alkali resistance and acid resistance. The filter of the present invention is produced by preparing an aggregate comprising alumina coarse particles and a sintering aid comprising alumina-zirconium mixed particles containing not more than 90 wt.% of alumina, blending said alumina coarse particles and alumina-zirconium mixed particles so as for alumina to be in an amount of from 80 to 99 wt.% based on the total weight of the starting materials, forming the blended starting materials to have a desired shape, and firing the formed product. &lt;IMAGE&gt;</p>
