Like zinc molybdate (ZnMoO₄), zinc tungstate is a compound composed of two transition metal elements and oxygen, gaining widespread attention from semiconductor researchers due to its unique structure and physicochemical properties. Note: Tungsten, zinc, and molybdenum are all transition metal elements; tungsten and molybdenum belong to the same subgroup, with atomic numbers 74 and 42, respectively, while zinc has an atomic number of 30.

From a chemical composition perspective, unlike sodium tungstate (Na₂WO₄) and potassium tungstate (K₂WO₄), 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.

Like sodium tungstate (Na₂WO₄), potassium tungstate is a tungstate composed of an alkali metal, a transition metal, and a non-metal element, exhibiting excellent thermal, mechanical, electrical, and optical properties. It is widely used in chemical and photovoltaic industries. Note: Tungsten is a transition metal element; sodium and potassium are alkali metals with atomic numbers 11 and 19, respectively.

Like calcium tungstate (CaWO₄), magnesium tungstate is an inorganic compound composed of a transition metal, an alkaline earth metal, and a non-metal element, exhibiting excellent optical, electrical, and magnetic properties, making it widely applicable in optoelectronics and chemical industries. Note: Both calcium and magnesium are alkaline earth metals, with atomic numbers 12 and 20, respectively.
