Method of preparing a diaphragm having a gel of a hydrous oxide of zirconium in a porous matrix

摘要

Disclosed is a method of preparing a hydrous zirconium oxide diaphragm by treating a porous matrix with ZrOCl2 and hydrolyzing the ZrOCl2 to ZrO2 with NH3. The disclosed method contemplates leaching out the NH4Cl, dehydrating the substrate, and sequentially building up the ZrO2.
