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 (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 tungsten (such as purity and particle size) are largely dependent on the reduction process. The main factors that affect the reduction process are: 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. The tungsten particles become coarser as the temperature of reduction increases.
This method is used in addition to the hydrogen-reduction method. This method yields tungsten with low purity. Moreover, research is being carried out on the reduction tungsten with metals such as aluminum, calcium, Zinc, etc. 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, 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. Another important use of tungsten is the preparation of cemented carbide products, such as turning and milling tools, drill bits, and molds.

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, 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, at a temperature between 500 and 700, tungsten dioxide is converted to tungsten oxide; the second at 900700. Tungsten is converted to tungsten. The reduction reaction takes place in a rotary or electric tube furnace.The properties of reduced powder tungsten (such as purity and particle size) are largely dependent 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, wear-resistant, and used for gas turbine blades, combustion tubes and tooling. 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.
