Phase equilibria in the YFeO3 – YСoO3 system in air
YFe1-xСоxO3 solid solutions were prepared by glycerol-nitrate technique. The homogeneity range of solid solutions was studied within the temperature range 1173 – 1573 K. A continues series of solid solution below the decomposition temperature of YСоO3, which was shown to be equal to 1266 ± 6 K, begi...

The phase diagram of the YFeO3 – YСoO3 system in the “T – composition” coordinates was divided into three fields.
