The Property and Application of Molybdenum Disulfide Powder

Molybdenum disulfide The main component in molybdenite is powder, which has the chemical formula MoS2. It is a dark solid powder that has a metallic sheen.

What property does molybdenum powder have?

The powder of molybdenum is not soluble with water, dilute sulfuric acid or other acids. It’s also generally not soluble with alkalis and organic solvents. But it can be dissolved in aqua regia (boiling concentrated sulfuric) and in concentrated sulfuric acetic acid.
It is easy for copper to be corroded by molybdenum powder, due to its high active sulfur content. In many books and articles on lubricant add-ons, it is mentioned. When parts made of copper alloys and copper need to be greased, it’s not impossible to use lubricants containing molybdenum sulfide, but you can also add copper corrosion inhibitors.

Where is molybdenum disulfide used?

Molybdenum diulfide is a very important solid lubricant. It is particularly suitable for use at high temperatures and under high pressure. It is diamagnetic and can be used to convert energy and as a linear semiconductor. Molybdenum Disulfide may also be used to dehydrate complex hydrocarbons.

The molybdenum diulfide is also called the “king of solid lubricants”. Molybdenum powder is solid molybdenum that has been purified chemically and changed in molecular structure. This product is black, has a slight metallic luster with a silvery gray tint, and is insoluble in liquid water. The product’s advantages are its good dispersibility, and that it is non-sticking. It can be mixed with various greases to produce a non-sticky, colloidal state. This can increase the lubricity of the grease and its extreme pressure. It can be used for mechanical conditions that require high temperatures, high pressures, high speeds, and high loads.

Its main purpose in friction materials is reducing friction at low temperature, increasing friction at higher temperatures and having a small loss during ignition. It is volatile in friction materials.

Molybdenum diulfide powder is also a potential new material to be used in the manufacture of transistors. In comparison with graphene (also a 2-dimensional material), molybdenum diulfide is has an energy gap of 1.8eV. Graphene lacks an energy gap. The application of molybdenum diulfide in nano-transistors is therefore very broad.

The Properties And Applications of Tungsten Powder

Tungsten powder The raw material used for the preparation of tungsten processing products, tungsten alloys, and tungsten goods is powdered tungsten.

Tungsten Powder Properties

Among all metals, the hardness of tungsten rods is the highest. The hardness ranges from 200-250 for sintered rods, while that of rods passed through the rotary hammer ranges between 350-400. Tungsten is dissolved in an acid mixture of hydrofluoric, nitric and sulfuric acids. It is then melted using a sodium hydroxide and carbonate 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 and sulfuric acids, as well as aqua regia. However, it is not soluble in water or hydrofluoric and potassium hydroxide.

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, the tungsten dioxide is converted to tungsten dioxide at a temperature between 500 and 700; the second is done at 700-900. 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. It is mainly determined by 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 tungsten Oxide in the burning boat and the speed of the boat. The particle size increases as the temperature of reduction rises.

This method is used in addition to the hydrogen-reduction method. The tungsten obtained from this method has a low purity. A research project on the reduction tungsten with metals such as aluminum, calcium and zinc is also underway. Research is also underway. This method can produce ultra-fine tungsten particles with a particle size less than 0.05mm.

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 niobium molybdenum etc. 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. 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 and rods. It can also be used to make tubes, plates, and other products. Tungsten powder can be mixed with other metal powders to create various tungsten alloys, including tungsten and molybdenum alloys, tungsten and rhenium, tungsten and copper alloys, as well as high-density alloys.
