The main role of tungsten wire in electric heated glass windows is to act as a heating element. By using its high resistance and high temperature resistance, the glass windows are heated by the resistance heat generated when the current flows through the tungsten wire to meet the various functional requirements such as anti-fogging, defrosting and temperature regulation.

Using tungsten wire to heat glass is usually used in laboratories or small process scenarios (such as glass tube sealing, wire drawing or local forming) because tungsten wire can provide high temperature and local heating. The following are typical steps for heating glass with tungsten wire:

Tungsten wire heating glass is suitable for processes that require high temperature and precise temperature control. The advantages are high efficiency and durability, but the problems of oxidation, cost and equipment complexity need to be solved. In practical applications, it is necessary to weigh the use according to the specific process requirements. The advantages and disadvantages of using tungsten wire to heat glass are as follows:

The application of tungsten wire in glass cutting mainly relies on its high strength, conductivity and high temperature heating ability. It can achieve precise cutting through thermal stress cracking, local softening or combined with abrasives and mechanical movement. It is particularly suitable for the processing of thin glass and optical components.

Tungsten wire has important applications in glass melting furnaces due to its high melting point (about 3422°C), excellent high temperature resistance and chemical stability, especially in the field of special glass and precision glass manufacturing. The following is a detailed introduction to its main uses and precautions.

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.

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.

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 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.

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.
