Tungsten trioxide is mainly used for calcination and reduction to produce tungsten powder and tungsten carbide powder, and then used to produce hard alloy products, such as the manufacture of knives and molds. At the same time, it can also be used to manufacture pure tungsten products, tungsten bars, tungsten wires, tungsten electrodes; and use as counterweight and radiation shielding materials. There is also a small amount of colorant used as a colorant for yellow ceramics in industrial production. In the shipbuilding industry, tungsten oxide is used as an important anti-corrosion paint and coating material. Yellow tungsten oxide has various applications in industry. It is an important raw material for the preparation of other tungsten compounds, and can be used as a precursor of tungsten alloys, tungstates, catalysts and pigments. Due to its absorbing and scattering properties in the visible range, yellow tungsten oxide is often used in products such as stained glass, ceramics, paints and plastics to give them a yellow tint. In addition, yellow tungsten oxide also has some special physical and chemical properties. It can be used as a resistor material because it exhibits high resistivity at high temperatures. In addition, yellow tungsten oxide can also be used in electrochromic materials and photocatalytic materials, which has potential application value.
Yellow tungsten has a wide range of uses in many fields, some of the main application areas of yellow tungsten are:
Electronic Device
Yellow tungsten is widely used in the manufacture of electronic devices, especially in electronic vacuum tubes, electric transistors and high-power semiconductor devices. Yellow tungsten’s high melting point, high electrical conductivity, and good thermal stability make it an important component in these devices.
Thermoelectric Material
Yellow tungsten has high resistivity and thermal conductivity, so it has important applications in the preparation of thermoelectric materials. It can be used to make thermocouples, thermistors, and temperature measuring devices, among others.
High Temperature Application
Due to its high melting point and heat resistance, yellow tungsten is often used in the manufacture of parts in high temperature environments, such as high temperature furnaces, vacuum furnaces, refractory materials and high temperature tools.
Photocatalytic Material
Yellow tungsten has certain photocatalytic properties and can be used in fields such as photocatalytic reactions, photovoltaic cells and photocatalytic water splitting.
Stains And Pigments
Yellow tungsten is used as a pigment in stained glass, ceramics, paints and plastics to give products a yellow tint.
Chemical Catalyst
Yellow tungsten can be used as a component of chemical catalysts to participate in redox reactions, acid-base catalysis and hydrogenation reactions.
In addition to the above applications, yellow tungsten is also used in other fields, such as material science, chemical industry, aerospace and medical equipment. It is necessary to control the morphology, structure and preparation method of yellow tungsten according to specific application requirements to achieve the best performance and effect.
