Tungsten powder
The raw material used for the preparation of tungsten processing products, tungsten alloys and tungsten goods is powdered tungsten.
Tungsten is a grayish-black metal that has a metallic sheen (body-centered cubic crystalline). 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 sizes composition, etc.). Basically, the reduction process determines how much tungsten powder is reduced. In a tube oven, when reducing the tungsten, the main parameters affecting the reduction rate include the reduction temperature. Other factors are the tungsten oxide loading in the burning boat. As the temperature of reduction increases, the particle sizes of the tungsten become coarser.
This method is used in addition to the hydrogen-reduction method. This method yields a relatively low-purity tungsten. In addition, work is being done 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 formed into plates, tubes, and products of certain shapes. Tungsten powder can be mixed with other metals to create various alloys. These include tungsten and copper alloys, tungsten and molybdenum alloys, and high-density alloys. Another important use of tungsten is the preparation of cemented carbide tools like turning tools, milling tools, drill bits, and molds.

Tungsten Powder Properties
The hardness is highest among all metals. The hardness ranges from 200-250 for sintered rods, and 350-400 for rods 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 (body-centered cubic crystalline). Tungsten powder has a slight solubility in nitric, sulfuric, and aqua regia acids; however, it is not soluble in water.
Tungsten Powder Preparation
The preparation of Tungsten Powder is done by hydrogen reduction. The preparation of tungsten powder using the hydrogen reduction method can be divided into two steps: in the first step, at 500-700°C, the tungsten dioxide is converted to tungsten oxide; and the second at 700-900°C, or at 700-900°C. Tungsten is converted to tungsten. The reduction reaction takes place in a rotary oven or an electric tube.The properties of reduced powder (such purity, particle sizes, particle sizes composition, etc.).

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 turbines blades and combustion tube. 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.
