Calcium Tungstate 11

From a chemical composition perspective, unlike sodium tungstate (Na?WO?) and potassium tungstate (K?WO?), where the cations (Na? and K?) are alkali metals, the cation in calcium tungstate (Ca2?) is an alkaline earth metal. This leads to slight differences in structure, physicochemical properties, production processes, and applications. Note: Sodium and potassium are both alkali metal elements. From a definitional standpoint, calcium tungstate, also known as “synthetic scheelite,” is a tungstate composed of divalent calcium ions (Ca2?) and tungstate ions [(WO?)2?]. It…
