Composition and process for preparing compound metal oxides.

摘要

A composition for forming a compound metal oxide of a specific compsotion and a process for preparing said compound oxide are disclosed. The composition comprises an alkoxide of a rare earth metal, an alkoxide of an alkaline earth metal and an organic acid salt of an organic complex of copper. The process comprises refluxing said composition for reaction and thermally decomposing the reaction product. Also a film-forming composition for forming a thin layer of a compound metal oxide is disclosed. Said film-forming compound comprises the above-mentioned composition plus a film forming resin and an organic solvent.
