Abstract

Phase equilibria at subsolidus area of quasi-triple BiO_1.5–CaO–CoO_y system in air have been studied. The formation of triple oxide Bi₂Ca₂Co_1.7O_x and limited number of solid solutions (Ca,Bi)₃Co₄O_9+δ has been established. The triangulation of BiO_1.5–CaO–CoO_y system in air at 973 K has been carried out.
