· Ca1 W1 O3

CaWO₄ (calcium tungstate) is an inorganic ceramic compound belonging to the scheelite mineral family, characterized by a tungstate crystal structure with potential semiconductor properties. This material is primarily investigated in research contexts for scintillation detection, luminescent applications, and solid-state physics studies, where its ability to emit light under ionizing radiation or ultraviolet excitation makes it valuable for radiation sensing and imaging applications. CaWO₄ is notable compared to alternatives like CdWO₄ (cadmium tungstate) due to its lower toxicity and environmental compatibility, though it is not yet a commodity engineering material in high-volume industrial use.
