Storage method: Sealed in a cool and dry place, in a cool environment, should not be exposed to the air, to prevent moisture oxidation agglomeration.
Manufacturing method
1. Reduction method: boron oxide and molybdenum oxide are reduced at high temperature in the presence of carbon
2. Molybdenum and boron powder react under vacuum conditions of 1300 ~ 1400℃.
3. When boron is steamed on molybdenum (or vice versa), molybdenum boride can be formed on the interface.
1. Ceramic coating: Molybdenum boride cermet has high hardness and low relative friction coefficient, the material is applied in sliding
The friction surface acts as a wear reducer. For example, molybdenum boride coating is applied to the inner wall of engine cylinder liner. Also due to the material
It has low reactivity with liquid zinc, and is used in foreign countries for continuous hot-dip galvanized submerged roller surface spraying material to protect submerged roller
Resistant to liquid zinc.
2. Molybdenum boride is used as an efficient catalyst for polysulfide REDOX for high energy density lithium-sulfur batteries. Molybdenum boride nanoparticles
The high electrical conductivity and abundant catalytic active centers make LIPS fast at the high sulfur supported electrode (6.1 mg cm-2)
Rapid REDOX kinetics. In addition, the hydrophilicity of molybdenum boride and its good wettability to the electrolyte can promote the electrolyte
Osmosis and REDOX of LiPS ensure high sulfur utilization under dilute electrolyte conditions.
3. Superhard materials: Each molybdenum atom of borides contains 4 to 5 boron atoms. MoB5 has a Vickers hardness of 37 to 39GPa,
This makes it a potentially superhard material.
Molybdenum boride has a very important position in modern industry, widely used in alloy materials, coating materials, high temperature structural materials
Materials, cathode materials, corrosion resistant materials, wear-resistant materials and other fields.
4. Molybdenum boride powder is considered to be a wear-resistant and corrosion-resistant material, and it is also a composite cermet material of iron and nickel boride
An important ingredient.
5. Molybdenum boride melting point at 2600℃, can do high temperature resistant spray layer. Good wear resistance, heat resistance, resistance and temperature
A special alloy with a linear relationship. It can be used in cermet, wear-resistant coating, high temperature resistance, pot lining, fill-in-blank spraying and coating
Corrosion resistant chemical equipment, transition metal borides are potential substitutes for traditional cemented carbide and high hard materials in technical applications.
And with the progress of science and technology, the application field of molybdenum boride compounds will be further expanded, and this material will be developed
Show more excellent application value and huge market prospects.
