· ZnI2

Zinc iodide (ZnI₂) is an inorganic ceramic compound composed of zinc and iodine, classified as a metal halide ceramic. It is primarily investigated as a scintillation material and radiation detector in nuclear and high-energy physics applications, where it offers the potential for efficient X-ray and gamma-ray detection. The material is also explored in photovoltaic research and specialized optics contexts; however, it remains largely in the research phase rather than widespread industrial production, making it most relevant for scientists and engineers developing advanced detection systems or exploring halide-based functional ceramics.
