Tungsten powder
The raw material used for the preparation of tungsten processing products, tungsten alloys, and other tungsten items is powdered tungsten.
Tungsten is a grayish-black metal that has a metallic sheen (cubic crystals with a body-centered). Tungsten powder has a slight solubility in nitric, sulfuric, and aqua regia acids; however, it is not soluble in water.
The properties of reduced powder (such purity, particle sizes, particle size composition etc.) depend mainly on the reduction process. The main factor is the reduction process. In a tube oven, when reducing the tungsten, the main process variables that affect the rate of reduction are the reduction temperatures, the loading of the tungsten oxide into the burning boat and its speed, as well as the flow rate of hydrogen. As the temperature of reduction increases, the particle sizes of tungsten become coarser.
This method is used in addition to the hydrogen-reduction method. The tungsten obtained from this method has a low purity. Moreover, research is being carried out on the reduction tungsten with metals such as aluminum, calcium and zinc. Research is also underway. This method can produce ultra-fine tungsten particles with a particle size less than 0.05mm.
High-density tungsten-nickel-copper alloy is used as a radiation shield. Metal tungsten wires, rods, sheets, etc. These are used for the production of electronic tubes, light bulbs and electrodes for welding. Tungsten can be sintered to create filters with different porosities.
Tungsten Powder is the main raw materials for powder metallurgy and alloys. Pure tungsten is processed into materials like wires or rods. It can also be shaped into plates, tubes, and certain products. Tungsten powder can be mixed with other metals to create various alloys. These include tungsten and copper alloys, tungsten and molybdenum alloys, tungsten and rhenium, high-density alloys. To prepare cemented-carbide tools such as turning tools and milling cutters or drill bits, tungsten can be made into tungsten rhenium powder.

Tungsten Powder Properties
The hardest metal in the world is tungsten. The hardness ranges from 200-250 for sintered rods, and 350-400 when tungsten is passed through the rotary hammer. Tungsten is dissolved in an acid mixture of nitric and hydrofluoric acids and then melted using a sodium hydroxide/sodium carboxide mixture.Tungsten is a grayish-black metal that has a metallic sheen (cubic crystals with a body-centered). Tungsten powder has a slight solubility in nitric, sulfuric, and aqua regia acids; however, it is not soluble in water.
Tungsten Powder Preparation
Tungsten is produced by hydrogen reduction. The preparation of tungsten powder using the hydrogen reduction method can be divided into two steps: in the first step, tungsten dioxide is converted to tungsten oxide at a temperature between 500 and 700; the second phase is carried out at 900700. Tungsten is converted to tungsten. The reduction reaction takes place in an electric tube or rotary furnace.The properties of reduced powder (such purity, particle sizes, particle size composition etc.) depend mainly on the reduction process.

Tunsten Powder Applications
Tungsten is used mainly in the productions of ferro tungsten and cemented carbide. Tungsten, chromium molybdenum and cobalt are combined to form an alloy which is heat resistant and wear-resistant. It can be used for making tools, surface hardening metals, gas turbine blades or combustion tubes. Tungsten, tantalum, molybdenum and niobium powders, for example, form a heat-resistant alloy. This alloy is refractory.High-density tungsten-nickel-copper alloy is used as a radiation shield.
