Barium Tungstate (BaWO4) is a crystalline compound with the chemical formula BaWO4. It is a white, cubic crystal with a high melting point, high density, and good chemical stability. It is widely used as a scintillation material, a component of radiation detectors, and as an active component in laser systems. Due to its high performance in the visible and ultraviolet spectral ranges, BaWO4 is commonly used as an optical crystal for high power laser applications and for optical components in spectrometers, polarizers, and wave plates.
