Overview of manganese carbide Mn3C powder:

Manganese carbide is a stable compound formed from manganese and carbon. The molecular formula is Mn3C, the melting point is about 1520°C, and the 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 to decompose, easy to react with chlorine and fluorine, and easy to decompose into manganese and carbon at high temperatures.

The heat of the formation of manganese carbide is △from(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 the heat reduced to metallic manganese or manganese silicide. That is, the reaction start temperature is relatively low. Therefore, high carbon ferromanganese contains more carbon. When smelting silico-manganese alloys, the generated manganese carbide Mn3C encounters silicon to generate silicide MnSi, which is more stable than Mn3C, and the carbon in Mn3C is squeezed out to obtain a manganese-silicon alloy.

Due to the complicated preparation process of electrolytic manganese metal, manganese carbonate ore and manganese oxide ore are mainly obtained by acid hydrolysis, impurity removal, and electrolysis. The manganese carbonate ore acid leaching method can directly use the chemical reaction of sulfuric acid and manganese carbonate to prepare manganese sulfate solution, and then prepare the electrolyte through a series of processes such as neutralization, purification, and filtration, and add additives such as selenium dioxide, ammonium sulfite, etc. Can enter the electrolytic cell for electrolysis; the process of manganese oxide reduction-acid leaching method to produce electrolytic manganese is different from the production process of manganese carbonate. The main reason is that manganese dioxide does not react with sulfuric acid under normal conditions and must be treated as divalent manganese Then it reacts with sulfuric acid to prepare a manganese sulfate solution. The treatment method is generally roasting, which is to mix manganese dioxide and a reducing substance (usual coal) together and then heat it in a sealed manner. C reduces the tetravalent manganese to two at a certain temperature. Manganese is smashed and then acid leached and impurity removed to obtain electrolyte. 2) The melting temperature is high, as high as 1300℃~1500℃. According to the analysis of the Mn-C binary phase diagram, the melting point of the Mn-C system is as high as 1300°C. In order to make the reaction complete, a high temperature must be ensured, and induction furnace smelting is often used. 3) Since the whole process is in a molten state, the material and refractory materials of the roasting equipment are required to be high. At present, my country's industry is developing in the direction of environmental protection and energy conservation. Therefore, it is of great practical significance to develop new technology for low-temperature, economical, clean, and efficient preparation of manganese carbide.

Application of manganese carbide Mn3C powder:

What are the application areas of manganese carbide Mn3C powder?

Manganese carbide Mn3C powder is used in hard coatings, indicators, welding materials, spray tools, steelmaking industry, aerospace, and other fields.

As a grain refiner for cermet and tungsten carbide, manganese carbide can significantly improve the properties of the alloy.

Manganese carbide can be used to prepare trimanganese tetroxide. Manganese tetroxide is one of the important raw materials for the production of manganese-zinc ferrite soft magnetic materials in the electronics industry, and it is widely used. According to reports, the manganese carbide hydrolysis method is one of the preparation methods of manganese tetroxide powder. Studies have disclosed a method for producing trimanganese tetroxide using carbon-manganese alloy, a one-step method for producing trimanganese tetroxide with low selenium and high specific surface area using carbon-manganese alloy, and the preparation of Mn3O4 nanopowder by manganese carbide hydrolysis and oxidation method. Manganese (transition metal carbide) hydrolysis oxidation method to prepare Mn3O4 powder does not involve catalysts, acids, alkalis, and other chemical reagents. Compared with the electrolytic metal manganese powder suspension oxidation method to prepare Mn3O4, it is obviously a veritable green Craft. However, the preparation of manganese carbide is the key to the preparation of Mn3O4 materials by manganese carbide hydrolysis. In this method, 92% of electrolytic metal manganese (high purity) and 8% of graphite are smelted in a 50kg induction furnace (temperature up to 1500℃), and the metal manganese and graphite are placed in a graphite crucible, and the graphite is broken into fine particles. The pellets make it melt as much as possible in the liquid phase alloy, and after the charge is fully melted, it is kept for a certain period of time, and then rapidly cooled to obtain a manganese carbide alloy block. The alloy block is crushed into powder. Then the obtained manganese carbide powder is subjected to oxidative hydrolysis reaction to prepare Mn3O4 material.

Manganese tetroxide is one of the important raw materials for the production of manganese-zinc ferrite soft magnetic materials in the electronics industry and has been widely used.

Manganese carbide can be used to prepare transformer oil. The method is simple and easy to implement, suitable for large-scale production, can prolong the replacement time of transformer oil, and reduce potential safety hazards.
