Zinc tungstate (ZnWO₄) is an inorganic ceramic compound combining zinc and tungsten oxide, belonging to the wolframite family of oxides. It is primarily used in phosphor applications, scintillation detectors, and specialty optical systems where its luminescent properties and radiation absorption characteristics are exploited. The material is notable for its use in X-ray and gamma-ray detection devices, medical imaging scintillators, and industrial radiation monitoring, where its high atomic number (tungsten) provides effective stopping power for energetic particles while maintaining reasonable mechanical integrity as a solid-state detector medium.
