Molybdenum Carbide’s main features
Molybdenum Carbide (Molybdenum Carbide), is a gray hexagonal crystalline. It is known for its high melting point, hardness, thermal and mechanical stability, as well as excellent corrosion resistance. The melting point is 2692degC. It is insoluble when mixed with water and lye. It can be slightly soluble in hydrofluoric, sulfuric, and nitric acid.
These are the main catalytic reactions that molybdenum caride uses:
1. Hydrogenation hydrogenolysis reactions
2. Hydrodesulfurization HDS or hydrodenitrogenation HDN;
3. Isomerization reaction
4. Hydrocarbon conversion, synthesis reaction
5. Application in ammonia synthesis.

The global consumption structure shows that molybdenum can be considered an ally of iron. Molybdenum is consumed in 80% of Western developed countries. Steel absorbs 30% of all molybdenum. Low alloy steel absorbs 30%. Drilling tools and cutting instruments account for 10%. Cast steel accounts 10%. The remaining 20% of molybdenum is consumed in molybdenum chemical, molybdenum-based lubricants, and petroleum refining. In the United States, 75% of the molybdenum used in steel production was quite common in 1998.
Additionally, molybdenum based alloys are becoming more common in electronics, metal processing, aerospace, and other industries.
The most popular molybdenum alloy, TZM alloy is known for its high strength and extensive properties. The United States uses TZM alloy to make the turbine disc of its engine. It accounts for 15% in total molybdenum. There are 22 grades of molybdenum, including TZM alloys. In my country, molybdenum production was almost 200 tons in the 1990s.
The high mechanical characteristics of TZM or TZC molybdenum alloys are better than pure, molybdenum. They are widely used in high-tech, mold, and other structural parts manufacturing. Since the 20th Century, we have successfully used them to make seamless steel pipes’ hot perforated heads. Powder metallurgy technology’s sintered molybdenum plug reduces the amount of raw material (50% in the as-cast condition) and extends the service life 1.5 to 2x.
This seamless tube, made from molybdenum/rhenium alloy (containing 50% Re), is extremely durable and can be used at temperatures close enough to its melting temperature.
The advantages of molybdenum, molybdenum, and molybdenum-alcohol alloys include high strength, excellent electrical and thermal conductivity, low thermal expansion coefficient, and similarity to glass used in electronic tube (grids & anodes), as well as being more easy to process than tungsten. So, plates, strips and foils are used in electronic tubes, electric light sources (supporting material), parts, and metal processing tools (diecasting and extrusion dens, forging s, forging, liquid metal screens, turbine disks) and turbine disks These components are widely used.
2. Alloying steel elements
Molybdenum is an allies to steel. It can be combined with nickel and chrome as alloying elements to reduce embrittlement which often occurs during heat treatment in alloy steels. American has found a solution to the shortage in tungsten resources by using molybdenum as a substitute for tungsten in its high-speed stainless steel. According to research, molybdenum can have twice the power of tungsten. A steel that contains 18% tungsten could be replaced with steel that contains 9% molybdenum by adding chromium, vanadium and chromium simultaneously. This drastically reduces the steel production cost. The purpose of molybdenum, which is a component of stainless steel, is to increase corrosion resistance and increase strength. You can see that molybdenum has a significant role in the iron- and steel industry.
