Molybdenum Carbide– Properties and Applications |

What is Molybdenum Carbide (or )?

Molybdenum Carbide is chemically named MoC with a molecular mass of 107.95

It has high melting points and hardness, excellent thermal and mechanical stability, as well as good corrosion resistance.

Molybdenum Carbide (gray hexagonal crystal) is a molybdenum carbide. It has a high melting temperature and hardness, excellent thermal and mechanical stability, as well as corrosion resistance. Its melting point is 2692degC. It is insoluble when mixed with water and lye. It can be slightly soluble in hydrofluoric, sulfuric, and nitric acid.

Molybdenum Carbide is used to:

1. Molybdenum-alloy

The most popular molybdenum alloy, TZM, is known for its high strength and extensive properties. The United States uses TZM alloy to make turbine disks. This alloy accounts for 15% in total molybdenum. There are 22 molybdenum grades in my country, including TZM. In the early 1990s my country had a nearly 200-ton production of molybdenum materials and molybdenum products.

The high mechanical properties of TZM molybdenum alloys and TZC molybdenum alloys are superior to pure molybdenum. They are widely used in high-tech molds and various structural parts. My country has been making them into seamless steel pipes thermal perforated plugs since the early 20th century. This sintered molybdenum-plug made with powder metallurgy technology lowers the amount of raw material (50% less than the as-cast state), and has a 1.5 to 2-fold increase in service life.

The molybdenum/rhenium-alloy seamless tube (containing 50% Re), is extremely high performing and can be used at temperatures close enough to its melting temperature. It can also be used as a bracket, ring or grid in the electron tube cathode.

Molybdenum or molybdenum-alcohols have a high strength, good electrical conductivity and low thermal expansion (similar to electron tube glasses), and also have the advantage that they are easier to process than tungsten. You will find plates, strips and foils as well as tubes, wires, wires and profiles. These are used in electronic tubes, anodes and grids, electric light sources (support material), parts and metal processing tools (die-casting, extrusion and forging dies), turbine discs and perforated plugs. These components are extensively used.

2. Alloying steel elements

Molybdenum is an allies with steel. This alloying element, along with nickel, chromium and chromium can reduce embrittlement that occurs in alloy steels when heat treatment takes place. High-speed steels are being made with molybdenum as a replacement for tungsten. Calculations have shown that molybdenum can twice the “capacity” of tungsten. The steel that contains 18% of tungsten can be substituted by the steel that has 9% molybdenum. (Chromium and vanadium are also added together), this greatly reduces steel’s cost. Molybdenum plays an important role in stainless steel’s corrosion resistance, high strength and weldability. It is clear that molybdenum plays a unique role in steel industry.

3. Other apps

Molybdenum is extremely low in vapor pressure at both vacuum furnace temperatures and working temperatures. Molybdenum parts are the most pollutant to furnace workpieces. The evaporation loss of high molybdenum elements, such as heat insulation encapsulation and heating elements, will not reduce their service life.

Molybdenum’s high strength makes it an ideal electrode for processing and equipment during rapid heating. Mollybdenum is chemically compatible to most glass components and will not cause color changes. The life expectancy of a glass melting furnace heating electrode can be up to three to five years.

4. Emerging applications

A molybdenum disilicide-based advanced composite material (MoSi2) is the best way to fix the problems of low molybdenum ductility and high molybdenum oxidation.

Molybdenum Carbide’s excellent mechanical, electrical and thermal properties make it a popular choice for advanced composite materials.
