Scandium zirconium ceramic electrolyte sheet and preparation method thereof

The invention relates to a scandium zirconium ceramic electrolyte sheet and a preparation method thereof. The method comprises steps that well-formed spherical scandium zirconium ceramic powder precursor is prepared by adding ionic crosslinking agent through the coprecipitation method, the precursor does not need washing, drying and calcination after filtration, binder, plasticizer and solvent aredirectly added, tape casting after ball milling is performed, a blank of a ceramic sheet is obtained, the blank is dried and then subjected to glue discharge, and the scandium zirconium ceramic electrolyte sheet is finally obtained through calcination. The method is advantaged in that the process is short, the process of preparing the scandium zirconium ceramic powder through washing, drying andcalcination of the precursor in the prior art is omitted, the prepared ceramic sheet has density greater than 95%, and conductivity reaches 0.15-0.18S/cm. 本发明涉及一种工艺简单易操作的钪锆陶瓷电解质片及其制备方法，先用共沉淀法通过加入离子交联剂制备形貌良好的球形钪锆陶瓷粉体前驱体，前驱体过滤后无
