What is Molybdenum Carbide exactly?
Molybdenum Carbide is chemically named MoC with a molecular mass of 107.95
It exhibits high melting point, hardness, thermal and mechanical stability as well as good resistance to corrosion.
Molybdenum Carbide (gray hexagonal crystal) is an example of a Molybdenum Carbide. This material has a high melting temperature and hardness. Additionally, it is stable at both thermal and mechanical temperatures and resists corrosion. It is insoluble in water, lye and sulfuric acid.
Molybdenum Carbide is used to:
1. Molybdenum alloy
The most popular molybdenum alloy, TZM-alloy has high strengths and excellent comprehensive properties. The United States utilizes TZM alloy for making turbine disks. It accounts for 15% the entire molybdenum content. There are 22 types of molybdenum products in my country, including TZM. Nearly 200 tons of molybdenum was produced in my country by the beginning of 1990.
The mechanical properties of TZM molybdenum alloys are superior to pure molybdenum. They are extensively used for the production of molds, high-tech parts, and many other structural components. They have been used in various seamless steel pipe and thermal perforated pipes since the beginning of the 20th century. This type of sintered molybdenum plugged made using powder metallurgy technologies reduces the use of raw materials (50%) and increases the average service lifespan by 1.5- to 2 years.
A seamless tube of molybdenum – rhenium alloy, containing 50% Re has outstanding high performance. This tube can also be used to make the brackets, rings, grids, and other parts for thermowells and electron tube cathodes.
Molybdenum, molybdenum alloys and other alloys are not only stronger than tungsten but have good electrical and thermal conductivity. You will find plates, profiles and strips in a variety of materials, including foils, tubes, sheets and foils. These are commonly used in electronic tubes, anodes and grids as well as parts and metal processing tools such die-casting, extrusion and forging dies and turbine disks. These components are extensively used.
2. Alloying steel elements
The alloying elements molybdenum and nickel can help reduce embrittlement, which is a common problem in all-alloy steels. High-speed steels are being made with molybdenum as a replacement for tungsten. Molybdenum, according to calculations has twice the “capacity” of tungsten. The steel that contains 18% of tungsten can now be replaced with the steel that has 9% molybdenum. Moreover, chrome and vanadium can be added together. This greatly lowers steel’s production costs. In stainless steel, molybdenum plays a vital role in improving corrosion resistance and strength. It also improves weldability. You can clearly see that molybdenum is an important component of the steel industry.
3. Additional apps
Molybdenum is very low in vapor pressure at both vacuum furnace temperatures and work temperature. Molybdenum is the most polluting part of the furnace. The evaporation loss won’t affect high molybdenum items such as heating elements or heat insulation encapsulation.
Molybdenum’s high strength makes it an ideal material for electrodes and equipment used in rapid heating. Mollybdenum has a chemical compatibility with many glass components. It will not cause any harmful color effects by allowing a tiny amount to dissolve in the glass melting tray. The life expectancy of a molybdenum heating electrode can reach 3 to 5 year in a glass melt furnace.
4. New applications
A molybdenum disilicide-based advanced composite material (MoSi2) is the best way to fix low ductility of molybdenum and high oxidation.
Molybdenum Carbide’s excellent mechanical, electrical and thermal properties make it a popular choice for advanced composite materials.
