Zusammenfassung:FIELD: power source materials. SUBSTANCE: invention relates to manufacturing high-dense ceramics for solid zirconium dioxide electrolyte with small aluminum oxide additives prepared by chemical precipitation from zirconium and aluminum chloride solutions. Ball grinding with surfactants and simultaneous stirring of superdispersed yttrium oxide additive (up to 2-3 mol %) are performed followed by molding and sintering accompanied by stabilization from monoclinic into cubic crystalline phase. Size of sintered crystals is below 2 mcm. Method makes it possible to manufacture strong sensitive elements of motor-car oxygen sensors with homogeneous distribution of additives. EFFECT: improved quality of electrolyte. 3 cl, 1 tbl
