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.

Tungsten wire is widely used in the manufacture of electric heated glass due to its high melting point, low evaporation rate and excellent thermal properties. It is used as a heating element to achieve defog, defrost or insulation functions. Electric heated glass usually generates heat after power is turned on by embedding tungsten wire in laminated glass or coating conductive film on the surface of glass to achieve functions such as light transmission and insulation.

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.

The performance of tungsten wire in glass heat treatment is mainly related to its unique physical and chemical properties. The following is an analysis of its performance:
