ceramic

· RbHgF3

RbHgF3 is a fluoride-based ceramic compound combining rubidium, mercury, and fluorine into a perovskite-like crystal structure. This is a research material studied primarily in solid-state chemistry and materials science; it is not widely deployed in commercial engineering applications. The compound is of academic interest for understanding halide perovskite properties and their potential in emerging technologies such as photovoltaic devices, ion conductors, or optical materials, though practical applications remain largely experimental due to mercury's toxicity and volatility concerns.
