Molybdenum Carbide has the chemical formula MoC. Its molecular weight 107.95.
The material is known for its high melting and hardness points, thermal and mechanical resistance, and corrosion resistance.
Molybdenum Carbide has a hexagonal gray crystal. It has a high melting and hardness point, as well as good mechanical and thermal stability. The melting temperature is 2692degC. It is insoluble in water, lye and sulfuric acid.
1. Molybdenum Alloy
TZM is the alloy with the highest strength and most comprehensive properties. The United States uses TZM for turbine disks, which account for 15 percent of the total molybdenum. In my country, we produce no less than 22 types of molybdenum material. This includes TZM molybdenum. Early 1990s, the output of my country in molybdenum alloys and molybdenum was around 200 tons.
TZM and TZC alloys have superior mechanical properties than pure molybdenum and are widely used to manufacture high-tech moulds and structural parts. In the early 20th century, my nation successfully produced them as thermally perforated seamless steel pipe plugs. The sintered molybdenum plugged made using powder metallurgy technology can reduce raw material consumption (50%) and improve the average service life of 1.5 to 2x.
The seamless tube of molybdenum and rhenium (containing 50% Re), has excellent high-performance, and can be used near its melting temperature. It can also be used to make the brackets, rings, grids, and other parts for thermowells or electron tubes.
It is easier to work with molybdenum than tungsten. The plates, strips and foils can be used to make tubes, rods wires profiles etc. These are used to make electronic tubes (grids), electric light source parts (support material), metal processing tool (die-casting dies, extrusion dies forging dies perforated plugs liquid metal screens), and turbine discs. Used in many components.
2. Alloying components of steel
As an alloying component, molybdenum with nickel and chromium can help reduce the embrittlement of alloy steels that occurs when heat is applied. The use of molybdenum in high-speed alloys to replace the tungsten is a leading solution for the tungsten resource shortage. Molybdenum, according to calculations has twice the capacity of tungsten. The steel that contains 18% tungsten is replaced by steel containing only 9% molybdenum. Molybdenum’s role in stainless steel is to enhance corrosion resistance, strength and weldability. You can see that molybdenum has a major role to play in the steel sector.
3. Other apps
Molybdenum exhibits a very low vapour pressure when working at the pressure and temperature of a vacuum furnace. Molybdenum is the material that causes the least contamination to the materials and workpieces inside the vacuum furnace.
Due to its high strength, molybdenum makes the ideal electrode in glass manufacturing. It is also the most suitable processing equipment and electrode during rapid heating. Because molybdenum is chemically incompatible with most glass components, it will not produce harmful color changes due to the small amount of molybdenum that may be dissolved in a glass melting tank. It can last up to five years as a heating electrode in a glass melting oven.
4. Emerging applications
Molybdenum diilicide (MoSi2) is a composite material that can be used to overcome the low ductility, high oxidation and low ductility problems.
Molybdenum Carbide has excellent properties in terms of electrical, mechanical, and thermal properties. It is widely used as a composite material in advanced composites.
