Product performance: VB2 has the characteristics of high melting point, high hardness, good electrical and thermal conductivity, resistance to molten metal erosion, etc.
It can be used to make ultra-high temperature structural materials, and has important applications in extreme environments such as ultra-high temperature and metal smelting. In addition,
As an alkaline battery electrode material, VB2 has a large discharge capacity and is a new type of energy material. Can also be used for derivation
Electric ceramic materials and other fields.
Purpose:
1. Metal borides can be used to produce batteries or fuel cells, which can be an alternative energy source for petroleum resources. Through metal
Electrochemical energy storage techniques for the multi-electron oxidation of borides such as vanadium boride are expected to be based on the Chemicalbook generation
Single-electron charge storage in existing batteries. Multi-electron oxidation of a vanadium boride anode coupled with a carbon-air cathode provides excellence
The electrochemical energy storage capacity is due to its multi-electron charge storage capacity.
2. Used in conductive ceramic materials, fine ceramic raw material powder and other fields, belongs to atomic crystals.
3. Vanadium boride can also be used for wear-resistant coating, vanadium boride coating has high hardness H≥35GPa, friction coefficient is 0.4 ~ 0.6
4. Semiconductor film
