Abstract
Perovskite-type oxyfluoride systems, ABO3-BaLiF3 (A=Ba, Ca and B=Ti, Zr) were investigated. In the Ba(Ti1-xLix)O3(1-x)F3x system, cubic phases appeared in the range, 0.2≦x≦0.4. In the (Ca1-xBax)(Zr1-xLix)O3(1-x)F3x system, orthorhombic phases different from CaZrO3 appeared in the range, 0.4≦x≦0.5. The lattice volumes of the new phases were larger than those of the respective end-members. On the other hand, the Ca1-xBaxTi1-xLixO3(1-x)F3x samples showed two phases of CaTiO3 and BaLiF3, of which lattice constants were almost independent of the composition.
