Tungsten powder
It is powdered steel tungsten. This raw material is used in the preparation of tungsten processing materials and alloys.
Tungsten (a gray-black metal) is characterized by metallic luster and body-centered cubic crystals. Tungsten powder can be dissolved in some acids, including sulfuric acid and aqua regia. However, it cannot dissolve in water and hydrofluoric.
Reduced tungsten powder has properties such as purity, size and composition. The process of reduction is key to the properties. Reduce tungsten powder using a tube furnace. The key process parameters that impact the reduction rate include the temperature, burning speed and loading of tungsten oxide into the burning boats. With increasing reduction temperatures, the size of the particles in tungsten powder gets smaller.
Other than the hydrogen reduction process, tungsten is also prepared using the tungstenoxide carbon reduction method. The reduction temperature is greater than 1050. It is possible to obtain tungsten powder with a very low purity. Additional research is underway on how to combine tungsten oxide and metals like aluminum, calcium, or zinc. This work is still ongoing. Special applications that need tungsten-powder with very fine particle sizes, such as those for high purity, have been made possible by the use of the tungsten chlorine hydrogen reduction process. The particle size of the powder obtained can not exceed 0.05mm.
High-density tungsten-nickel-copper alloy is used as a radiation shield. Metal tungsten wires, rods, sheets, etc. They are used in the manufacture of parts for light bulbs and electronic tubes. You can make filters from tungsten powder.
For processing powder metallurgy and tungsten compounds, tungsten powder is the primary raw material. You can make tungsten powder into wires or rods. You can make tungsten mixtures from tungsten and other metals like tungsten-molybdenum alloy, tungsten rhenium alloy, tungsten copper alloy, and high-density-tungsten alloy. The preparation of cemented carbide tools using tungsten-carbide powder, like turning tools, drill bits and moulds, is another important function for tungsten.

Tungsten Powder Properties
Tungsten has the highest hardness among all metals. Hardness for sintered tungsten spheres ranges from 200 to 250, while hardness for tungsten rods passed through a rotating hammer is between 350 and 400. Mixture of hydrofluoric acids and nitric Acid is used to dissolve tungsten powder. Then, it’s melted using a mixture sodium hydroxide/nathan carbonate.Tungsten (a gray-black metal) is characterized by metallic luster and body-centered cubic crystals. Tungsten powder can be dissolved in some acids, including sulfuric acid and aqua regia. However, it cannot dissolve in water and hydrofluoric.
Tungsten Powder Preparation
The hydrogen reduction or ammonium paratungstate of tungsten trioxide is what makes tungsten powder. Two stages are used to make tungsten powder. At 500 -700 the tungsten dioxide is reduced into tungsten dioxide. At 700 -900 the second stage, which is at 700 900, is the final stage. Reduced tungsten to a powder. This reaction can be carried out either in an electric tube furnace (or a rotary furnace).Reduced tungsten powder has properties such as purity, size and composition.

Tunsten Powder Applications
Most commonly, tungsten is used to produce cemented caride and ferro-tungsten. Combining tungsten powder and chromium, molybdenum or cobalt, it forms a wear-resistant and heat-resistant alloy that is useful in making tools, metal surface hardening material, combustion tubes, blades for gas turbines, and other devices. Tungsten powder, tantalum or niobium as well as molybdenum and molybdenum can be used. For refractory alloys,High-density tungsten-nickel-copper alloy is used as a radiation shield.
