Compounds in a CaO–Y 2 O 3 –SnO 2 system were prepared by a solid‐state reaction at 1673 K. The phase relation in this system was investigated by powder X‐ray diffraction. Besides the previously reported ternary compounds, CaSnO 3 , Ca 2 SnO 4 , Y 2 Sn 2 O 7 , and a quaternary compound Ca 0.4 Y 1.2 Sn 0.4 O 3 , solid‐solution series of Ca 2− x Y 2 x Sn 1− x O 4 with 0≤ x ≤0.5, and Ca 1− y Y 2 y Sn 1− y O 3 with 0≤ y ≤0.2 and 0.95≤ y ≤1.0 were found. The cell parameters of these solid‐solution series were refined. The changes of rhombohedral cell parameters in the samples prepared in the range 0.565< y <0.714 of Ca 1− y Y 2 y Sn 1− y O 3 suggested the existence of solid solutions of Ca 0.4 Y 1.2 Sn 0.4 O 3 , although their single phases could not be prepared, except at y =0.6.
