Rubidium niobate (RbNbO₃) is a perovskite ceramic semiconductor combining alkali metal and transition metal oxide components. This material is primarily explored in research and advanced applications rather than established industrial production, with potential use in ferroelectric devices, electro-optic modulators, and photonic systems where its perovskite structure enables tunable electrical and optical properties.
