What is Molybdenum Carbide?
Molybdenum carbide is a transition metal carbide, which is a family of interstitial compounds with metallic properties formed by carbon entering the crystal lattice of transition metals.
The main features of Molybdenum Carbide
Molybdenum Carbide (Molybdenum Carbide) is a gray hexagonal crystal. It has the characteristics of high melting point and hardness, good thermal and mechanical stability and good corrosion resistance. The melting point is 2692°C. Insoluble in water and lye, slightly soluble in nitric acid, sulfuric acid and hydrofluoric acid.
The main catalytic reaction types of molybdenum carbide:
1. Hydrogenation hydrogenolysis reaction;
2. Hydrodesulfurization HDS and hydrodenitrogenation HDN reaction;
3. Isomerization reaction;
4. Hydrocarbon conversion and synthesis reaction;
5. Application in ammonia synthesis.

The applications of Molybdenum Carbide
From the perspective of the global consumption structure, molybdenum is indeed an ally of iron. 80% of the demand for molybdenum in western developed countries comes from steel, stainless steel absorbs 30% of molybdenum, low alloy steel absorbs 30%, drilling bits and cutting tools account for 10%, and cast steel accounts for 10%. Another 20% of molybdenum consumption is in molybdenum chemicals, molybdenum-based lubricants and petroleum refining. Quite typical in the United States in 1998, the proportion of molybdenum consumption in steel production was 75%.
In addition, molybdenum-based alloys are increasingly widely used in electronics, metal processing and aerospace industries.
1. Molybdenum alloy
TZM alloy has excellent high strength and comprehensive properties, and is the most widely used molybdenum alloy. The United States uses TZM alloy to make the turbine disk of the engine, and the amount of molybdenum used accounts for 15% of the total amount of molybdenum. The production of molybdenum materials including TZM molybdenum alloys in my country is no less than 22 grades. In the early 1990s, the output of molybdenum and molybdenum products in my country was nearly 200 tons.
The high mechanical properties of TZM and TZC molybdenum alloys are better than pure molybdenum, and are widely used in the manufacture of high-tech, mold and various structural parts. As early as the 20th century, our country has successfully made them into hot perforated heads of various seamless steel pipes. The sintered molybdenum plug manufactured by powder metallurgy technology reduces the consumption of raw materials (50% of the as-cast state) and increases the average service life by 1.5 to 2 times.
The seamless tube made of molybdenum-rhenium alloy (containing 50% Re) has excellent performance and can be used at a temperature close to its melting point.
In addition to high strength, good electrical and thermal conductivity and low thermal expansion coefficient (similar to the glass used in electronic tubes), molybdenum and molybdenum alloys also have the advantage of being easier to process than tungsten, so plates, strips, foils, Tubes, rods, wires and profiles are used in electronic tubes (grids and anodes), electric light sources (supporting materials) parts, metal processing tools (die-casting and extrusion dies, forging dies, perforated plugs, liquid metal screens) and turbine disks, etc. components are widely used.
2. Alloying elements of steel
As an ally of steel, molybdenum, together with nickel and chromium as alloying elements, can reduce the embrittlement that often occurs in alloy steels during heat treatment. Using molybdenum instead of tungsten in high-speed steel has led the United States to solve the shortage of tungsten resources. It is calculated that molybdenum has twice the "power" of tungsten. In this way, steel containing 18% tungsten can be replaced by steel containing 9% molybdenum (adding chromium and vanadium at the same time), which greatly reduces the production cost of steel. The role of molybdenum in stainless steel is to increase corrosion resistance, increase high strength and improve weldability. It can be seen that molybdenum plays an extraordinary role in the iron and steel industry.
