Rb1 Ni1 O3

RbNiO₃ is a perovskite-structured ceramic oxide compound combining rubidium, nickel, and oxygen in a 1:1:3 stoichiometry. This is primarily a research material studied for its electronic and magnetic properties rather than an established commercial product. The compound is of interest in solid-state chemistry and materials research for potential applications in catalysis, solid electrolytes, and magnetic materials, though it remains largely in the experimental stage with limited industrial deployment compared to more common perovskites like lead titanate or barium titanate.
