Tungsten powder
The raw material used for the preparation of tungsten processing products, tungsten alloys and tungsten-based products 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 and sulfuric acids, as well as aqua regia. However, it is not soluble in water or hydrofluoric and potassium hydroxide.
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 the hydrogen. As the temperature of reduction increases, the particle sizes of the tungsten become coarser.
This method is used in addition to the tungsten-oxide carbon reduction method. The tungsten obtained from this method has a low purity. A research project on the reduction tungsten with metals such as aluminum, zinc, calcium, etc., is also underway. 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. Sintered filters can be created from tungsten.
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 made into tubes, plates, or products of certain shapes. Tungsten powder can be mixed with other metal powders to create various tungsten alloys, including tungsten and molybdenum, tungsten and copper, or high-density. The tungsten is also used in the production of tungsten carbide, which can be used for cemented carbide products such as turning tools and milling cutters.

Tungsten Powder Properties
The hardest metal in the world is tungsten. 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 and sulfuric acids, as well as aqua regia. However, it is not soluble in water or hydrofluoric and potassium hydroxide.
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, the tungsten dioxide is converted to tungsten oxide at a temperature between 500 and 700; the second is done at 900700. Tungsten is converted to tungsten. The reduction reaction takes place in an electric furnace, rotary oven or tube 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 turbines blades, and 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. Metal tungsten wires, rods, sheets, etc. These are used for the production of electronic tubes, light bulbs and electrodes for welding. Sintered filters can be created from tungsten.
