Chemical synthesis and granulometric composition of CaZr0.9Y0.1O3-delta powders

摘要

CaZr0.9Y0.1O3-delta powders were synthesized by chemical solution methods: modified Pechini method and from solutions of inorganic salts in water and ethanol. The structure crystallizes into the orthorhombic type upon annealing at 1000A degrees C for powders prepared by the Pechini method and from solution of salts in water. It was shown that CaZr0.9Y0.1O3-delta powders synthesized by various methods have different dispersities. The results obtained in a study of the granulometric composition by the sedimentation method and microscopic analysis enable fabrication of dense and mechanically strong electrolyte films and ceramics.
