Abstract

Synthesis of Highly Dispersed Barium Zirconate Using ZirconiumEthylenediaminetetraacetate.-Treatment of zirconyl chloride with EDTA followed by reaction with Ba(OH) 2 provides a non-hygroscopic powder of hydrated binuclear complexes of Zr and Ba. Thermal decomposition of these complexes affords a monophase submicron powder of BaZrO 3 having a skeleton type microstructure. -(MARTYNENKO, L. I.; SHLYAKHTIN, O. A.; MILO-VANOV, S.
