Summary:An organic zirconium complex was synthesised from concentrated ZrOCl2 solution and an organic complex which was a mixture of beta-glycosyl urea (Schiff's base) and urea. Homogeneous hydrolysis and controlled polymerisation of zirconium-tetramers was accomplished by heating the solution to boiling. Fine ZrO2 and yttrium- or magnesium-stabilised ZrO2 0.1 micron powders were prepared by dehydration and pyrolysis in air, and were sintered to an above 98% density ceramic with 0.25-0.30 micron grain size. 16 refs.
