Technical Parameter of Molybdenum Carbide Mo2C Powder:

How is Molybdenum Carbide Mo2C Powder produced?
1. Generally, molybdenum carbide powder is made first (using molybdenum and carbon direct chemical method, metal oxide and carbon reduction-chemical method, vapor deposition method and self-propagating high-temperature synthesis method), and then in a vacuum or reducing atmosphere in the carbon tube Furnace, molybdenum wire furnace, high-frequency vacuum furnace for sintering (reaction sintering, hot pressing sintering and hot isostatic pressing sintering are mostly used).
 
2. After the molybdenum powder and carbon black are fully mixed, they are ground by a ball mill and pressed into shape. In a hydrogen gas stream, the product is calcined at 1350-1500°C, and then the calcined product is cooled, crushed, and ground. Or use molybdenum trioxide or molybdenum dioxide instead of molybdenum powder reduction method.
 
3. Auxiliary metal bath method.
Using cobalt as the auxiliary metal, select Mo: Co to form a metal bath at a ratio of 1:(1~1.5), 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 1h) ℃, keep at 1800℃ for 2~3h, cooling to room temperature takes 2h), 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 150~350μm, 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.
 
4. Manufactured by the carbonization of metallic molybdenum.
Molybdenum trioxide MoO3 is hydrogenated and reduced to obtain molybdenum powder. Then the mixture of molybdenum powder and carbon black [Mo93 4% (mass) C6.6% (mass)] is dry-mixed with a ball mill for about 10 hours, and molded under pressure at a pressure of about 1t/cm2. Put the pressurized material block into a graphite pan or crucible, and heat it to 1400~1500 in a hydrogen stream (using pure hydrogen with a dew point of about -35℃) with a Taman furnace or an induction heating furnace (see picture) ℃, keep at this temperature for about 1h. Carbonize molybdenum to generate Mo2C.
 
5. Using synthetic methods.
First, the molybdenum powder is thoroughly mixed with carbon black [containing V6.6% (mass fraction)] according to Mo93.4% (mass fraction), then ground by a ball mill for 1 hour, pressurized to form, and put into an induction furnace. In hydrogen gas flow, calcining at 1350-1500°C for 1h, and then cooling, pulverizing and grinding the calcined product to obtain the product. Molybdenum trioxide or molybdenum dioxide can also be used instead of molybdenum powder for reduction to obtain molybdenum carbide.

Applications of Molybdenum Carbide Mo2C Powder:
Molybdenum carbide is a new functional material with a high melting point, high hardness and excellent anti-corrosion properties. It has been widely used in various high temperature, abrasion and chemical corrosion fields. It has a similar noble metal electronic structure and catalytic performance.
 
1. Due to its electronic structure and catalytic performance similar to noble metals, molybdenum carbide can be widely used as a catalyst for reactions involving hydrogens, such as the isomerization of alkanes, the hydrogenation of unsaturated hydrocarbons, hydrodesulfurization and denitrification;
2. Molybdenum carbide is an important component of molybdenum-molybdenum carbide hard coatings and other cermet coatings, and can also be used alone as a wear-resistant and wear-resistant coating;
2. Molybdenum carbide is widely used in hydrogen-related reactions such as alkanes;
3. Molybdenum carbide can be used to produce chromium-free special alloys and engineering ceramics;
