Processes for preparing ceramic microporous diaphragms based on aluminum and zirconium oxides are studied. Diaphragm test results for long-term corrosion resistance are presented. It is shown that ceramic material based on zirconium and aluminum oxides prepared at 1350°C with linear shrinkage of 75% has open porosity of 49% and ultimate strength in bending of 48 MPa. Diaphragms prepared from this material can withstand pressure up to 1.0 MPa and operate under aqueous chloride solution electrolysis conditions for at least 40,000 hours.
