Bimetallic Alkoxides of Barium and Zirconium: Preparation of BaZrO3 Powder

Complex formation in solutions of barium and zirconium alkoxides in ROH (R = i-Pr, Et) was studied. A number of bimetallic complexes were isolated, and their structure and properties were studied. The sol-gel method yields a single-phase BaZrO3 powder only when i -PrOH solutions of the alkoxides are...

Zusammenfassung:Complex formation in solutions of barium and zirconium alkoxides in ROH (R = i-Pr, Et) was studied. A number of bimetallic complexes were isolated, and their structure and properties were studied. The sol-gel method yields a single-phase BaZrO3 powder only when i -PrOH solutions of the alkoxides are used. In this case, the oxocomplex, BaZrO(OPr-i)2.(1–2)i-PrOH, is the precursor of the mixed oxide.
