Release time:2023.10.17Publisher:tungsten trioxide
The functions of tungsten trioxide are as follows:
Petrochemical field. Tungsten trioxide can be used as a catalyst. When used as a catalyst, it not only has high catalytic activity and long service life, but more importantly, it is environmentally friendly, non-toxic and pollution-free.
Optoelectronic information field. Tungsten trioxide has attracted much attention due to its good visible light response, environmental protection and non-toxicity, high economic benefits and relatively stable chemical properties under acidic conditions. For example, it has been used in the production of electrochromic windows.
National defense and military industry. Tungsten trioxide is often used as an important stealth material in military concealment because of its advantages of simple structure, high shielding and high sensitivity.

The processing of ferroalloy powder can be carried out through the following steps:Raw material preparation: Select appropriate ferroalloy powder, such as pure iron, low carbon steel, high carbon steel, etc., and prepare processing equipment, such as hydraulic press, die, grinding equipment, etc.
The advantages of resin tungsten powder mainly include:High density: Resin tungsten powder has a high density, which helps to improve product quality and performance.Good plasticity: Resin tungsten powder has good plasticity and can be processed into products of various shapes and specifications.
The molding process of alloy powder generally includes injection molding and compression molding.The press molding process requires the use of hydraulic press equipment for pressing.
High-purity tungsten carbide particles have the following performance characteristics:High hardness: The hardness of high-purity tungsten carbide particles is very high, reaching above HRA93.0, which makes it have excellent wear resistance and impact resistance.
The applications of high-purity tungsten powder mainly include the following fields:Cemented carbide preparation: High-purity tungsten powder is an important raw material for the production of cemented carbide and can be used to manufacture carbide tools such as turning tools, milling cutters, drill bits and molds.
Coarse-grained tungsten carbide is used to produce cemented carbide and can also be used as an additive for aerospace cables.Tungsten carbide is a metal carbide powder and an alloy powder.
The functions of tungsten trioxide are as follows:Petrochemical field. Tungsten trioxide can be used as a catalyst. When used as a catalyst, it not only has high catalytic activity and long service life, but more importantly, it is environmentally friendly, non-toxic and pollution-free.
Tungsten carbide particles are used in many industries due to its superior hardness properties compared to tool steels and superior toughness compared to technical ceramics.
As an important intermediate product of transition metal tungsten, tungsten powder has strong reducing properties and is often used to produce tungsten products such as tungsten oxide, tungstate, tungsten carbide, tungsten rods, and tungsten strips.
