Manganese Carbide Properties

About Manganese Carbide Mn3C Powder:

Manganese carbide is a stable compound formed by manganese and carbon. Manganese carbide formula is Mn3C, Manganese carbide melting point is about 1520°C, and Manganese carbide density is 6.89g/cm3. Manganese carbide burns rapidly in oxygen and decomposes in water to produce manganese hydroxide, methane, and hydrogen. It is easy to react with acid and be decomposed, easily react with chlorine and fluorine, and decompose into manganese and carbon at high temperatures.

The heat of the formation of manganese carbide is △fHm (298K)=-(15.06±12.55)kJ/mol. When smelting high-carbon ferromanganese or manganese-silicon alloy in a blast furnace or electric furnace, what is obtained is not pure manganese or manganese silicide but manganese carbide. Therefore, the heat absorbed by the reaction is less than that of reduction to metallic manganese or silicide. The reaction starts with the temperature is low. Therefore, high-carbon ferromanganese contains more carbon.

How is Manganese Carbide Mn3C Powder produced?
Carbothermal reduction method
The carbothermal reduction method is common for preparing manganese carbide, which is the reaction of coke or graphite with manganese oxide in an oxygen-free or weak oxidation atmosphere under high-temperature conditions. The reaction equation of this method is:
MnO2(s) + C(s) → Mn3C(s) + CO(g)
The reaction must occur at high temperatures, usually above 900 ° C. At the same time, the atmosphere in the reaction will affect the generation of manganese carbide; if there is a lot of oxygen, it will generate manganese dioxide. Therefore, to prepare high-purity manganese carbide, it is necessary to strictly control the reaction conditions. In addition, the coke or graphite used in the reaction needs to be rigorously treated to ensure that its impurity content is low, thus improving the purity of the manganese carbide.
Electrolytic method
Electrolysis is the process of using electricity to trigger chemical reactions. In the electrolysis process, manganese chloride and graphite are usually used as raw materials to generate manganese carbide by electrification in the electrolytic cell. The reaction equation of this method is:
MnCl2(aq) + 2C(s) → Mn3C(s) + 2Cl(aq)
Electrolysis can be performed at lower temperatures, usually around 800 ° C. At the same time, because the chemical reaction is generated by electrical energy, the reaction conditions and the structure of manganese carbide can be easily controlled. Additionally, the particle size and the morphology of manganese carbonite can be controlled with electrolysis by altering the frequency of the current and duration of electrolysis. However, the electrolysis method requires a lot of electricity, so the cost is higher.
Vapor deposition method
Vapor deposition is a method to deposit manganese carbide on the surface of the substrate by chemical reaction or physical deposition. This method uses raw materials from methane, hydrogen, nitrogen, and other gases. It reacts with manganese oxide under high temperature and pressure to generate manganese carbide and deposit it on the surface of the matrix. The reaction equation of this method is:
MnO2(s) + 4CH4(g) → Mn3C(s) + 2H2O(g) + 2H2(g)
The advantage of vapor deposition is that the manganese carbide coating can be directly formed on the substrate surface, so high purity and high-density manganese carbide coating can be obtained. At the same time, because the temperature and pressure of the vapor deposition method are adjustable, the coating's reaction conditions and thickness can be easily controlled. However, the equipment investment is large due to the need to use large reactors, precision control systems, and other equipment.
Mechanical alloying
Mechanical alloying is mixing metal or metal oxide powder by high-energy ball milling and ball milling to nanometer particle size. In the mechanical alloying method, metal oxide powder (such as manganese oxide) is mixed with metal (such as iron) powder and ball milling is carried out. And REDOX reaction occurs during the ball milling process, and manganese carbide is formed. The method has the advantages of simple equipment, convenient operation, and low production cost. However, the disadvantage of the mechanical alloying method is that it is difficult to prepare high-purity manganese carbide, and the prepared manganese carbide particle size is coarser.
