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 cobalt tungstate (CoWO₄) and nickel tungstate (NiWO₄), ferrous tungstate is an inorganic compound composed of transition metal elements, Group VIII elements, and non-metals, exhibiting excellent physicochemical properties and wide applications in the chemical industry. Note: Iron, cobalt, and nickel, known as iron-group elements, are all fourth-period, Group VIII elements with atomic numbers 26, 27, and 28, respectively. Their properties are similar, and they all display ferromagnetism.

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.

The application of tungsten wire in glass thermal processing is mainly due to its high melting point, high temperature resistance and good thermal stability. Tungsten wire is mainly used as a heating element in glass thermal processing, used in melting, drawing, sealing and laboratory processing.
