Abstract	BaBiO₃ has the perovskite structure, but tilting of the BiO₆ octahedra destroy the ideal cubic symmetry except at temperatures above 820 K. BaBiO₃ is a diamagnetic semiconductor due to a charge density wave (CDW), which is equivalent to a Ba₂Bi³⁺Bi⁵⁺O₆ representation. Recent calculations and experimental results confirm that there is no significant deviation from the oxidation states of 3+ and 5+. Superconductivity with a T[subscript c] as high as 13 K occurs for BaPb₁₋ₓBiₓO₃ phases where the 6s band is about 25% filled, and superconductivity with a T[subscript c] as high as 34 K occurs for Ba₁₋ₓKₓBiO₃ phases where the 6s band is about 35% filled. Structures in these two solid solutions can have cubic, tetragonal, orthorhombic, or monoclinic symmetry. However, superconductivity has only been observed when the symmetry is tetragonal.
