What is molybdenum carbide?

What is Molybdenum Carbide?
Molybdenum Carbide (MoC) with a molecular weight of 107.95. It has the characteristics of high melting point and hardness, good thermal and mechanical stability and good corrosion resistance. As a new type of functional material, it has a high melting point and hardness, good thermal and mechanical stability, and good corrosion resistance. It has been widely used in high-temperature resistance, wear resistance and chemical corrosion resistance.
 
Physicochemical property of Molybdenum Carbide Powder
Molybdenum carbide is a grey powder with a melting point of 2692, insoluble in water and alkali, slightly soluble in nitric acid, sulfuric acid and hydrofluoric acid, and has the characteristics of high melting point, high hardness, good thermal stability, mechanical stability, wear resistance and corrosion resistance. In addition, MoC has an electronic structure and catalytic characteristics similar to precious metals. The main types of catalytic reactions include hydrogenolysis, isomerization, hydrodesulfurization, hydrodenitrogenation, ammonia synthesis, hydrocarbon conversion and synthesis.
Production method of Molybdenum Carbide
1. Direct synthesis method:
Molybdenum and carbon are used as raw materials, then dry-mixed with a ball mill, fully mixed, pressed and moulded, then put into a heated graphite plate, Mo2C is initially generated, and then MoC is continuously reacted at high temperature to generate MOC. Chemical reaction formula: 2mo+c = mo2c; Mo+C=MoC
2. propanol reduction method:
putting molybdenum oxide into a reaction furnace, continuously introducing the mixed gas of propanol steam and argon, and controlling the temperature of the reaction furnace to carbonize molybdenum oxide in the furnace until molybdenum carbide is obtained; After the reduction and carbonization treatment, argon gas is continuously introduced into the reaction furnace so that all products cooled to room temperature is MoC.
3. Auxiliary metal bath method:
Using cobalt as the auxiliary metal, select Mo: Co to form a metal bath at a ratio of 1:(11.5), heat it in a pure graphite crucible with a Taman furnace in a hydrogen stream to 1800°C, and cool it (heating to 1800°C within one h) , keep at 1800 for 23h, cooling to room temperature takes two h), crush the solidified product in the crucible, treat it with warm hydrochloric acid, and dissolve and remove the cobalt, and then obtain powdered Mo2C with a particle size of 150350μm, the purity is: Containing 5.82%5.85% (mass) of bound carbon, 0.26%0.32% (mass) of free carbon, 6.08%6.17% (mass) of total carbon.
Uses of Molybdenum Carbide Powder
1. Production of molybdenum alloy. Molybdenum-titanium alloy and Molybdenum-titanium-zirconium-carbon alloy are widely used in electronic tubes, electric light source parts, metal working tools, turbine disks and other parts because of their high strength, good electrical conductivity and low thermal expansion coefficient.
2. as an additive for steel. The role of molybdenum in stainless steel is to improve the corrosion resistance, strength and weldability of products.
3. as a heating electrode in a glass melting furnace. Molybdenum has good compatibility with most glass components, and no harmful substances will be produced because a small amount of molybdenum is dissolved in the glass bath.
Price of Molybdenum Carbide Powder
Molybdenum Carbide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Molybdenum Carbide powder. A large amount of large amount will be lower. The price of Molybdenum Carbide powder can be found on our company's official website.
