· MgWO4

Magnesium tungstate (MgWO4) is an inorganic ceramic compound composed of magnesium and tungstate ions, typically employed in high-temperature and optical applications where chemical stability and thermal resistance are required. It is used primarily in scintillation detectors, X-ray phosphors, and specialized refractory applications where its thermal stability and radiation absorption properties provide advantages over conventional oxides. The material is also of interest in research contexts for photoluminescence and sensing applications, though it remains less common than broader ceramic families like alumina or zirconia in mainstream engineering.
