CAS 7790-75-2

Calcium tungstate

Description:

Calcium tungstate, with the chemical formula CaWO₄ and CAS number 7790-75-2, is an inorganic compound characterized by its white crystalline appearance. It is a tungstate mineral that occurs naturally as the mineral scheelite. Calcium tungstate is known for its high density and is insoluble in water, making it stable under various conditions. It exhibits a tetragonal crystal system and has a high melting point, which contributes to its utility in various applications. One of its notable characteristics is its fluorescence; when exposed to ultraviolet light, it can emit visible light, making it useful in certain lighting and display technologies. Additionally, calcium tungstate is used in the production of phosphors, in radiation shielding, and as a contrast agent in medical imaging. Its non-toxic nature and compatibility with biological systems also make it a candidate for various biomedical applications. Overall, calcium tungstate is a versatile compound with significant industrial and scientific relevance.
