VERFAHREN ZUR HERSTELLUNG EINER KERAMIKZUSAMMENSETZUNG

摘要

A method of producing a ceramic composition having a chemical composition represented by the following general formula: Pb1-xLax(ZryTi1-y)1-x/4 3 (wherein 0<x<1, 0<y<1), comprises mixing an aqueous solution containing lanthanum nitrate and/or lanthanum acetate with a mixed solution prepared by mixing lead alkoxide, zirconium alkoxide and titanium alkoxide thereby effecting hydrolysis of the alkoxides and coprecipitation of lanthanum components, and heating the thus obtained precipitates.
