Synthesis method: element boron and element niobium are mixed in proportion,
pressed and formed, and heated in a heating furnace.
Product performance: VB2 has the characteristics of high melting point, high hardness,
good conductivity and heat conductivity, and can resist molten metal corrosion. 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, VB2, as the electrode material of alkaline battery, has a large discharge
capacity and is a new energy material. It can also be used in conductive ceramic materials
and other fields.
Metal borides can be used to produce batteries or fuel cells, which can be alternative
energy for oil resources. Electrochemical energy storage technology through multi
electron oxidation of metal borides, such as vanadium borate, is expected to replace
existing batteries based on single electron charge storage for chemicalbook. The multi
electron oxidation of vanadium borate anode coupled with carbon air cathode can
provide excellent electrochemical energy storage capacity, which is due to its multi
electron charge storage capacity.
2. It is used in the fields of conductive ceramic materials, fine ceramic raw material powder
and belongs to atomic crystals.
3. Vanadium borate can also be used for wear-resistant coating. Vanadium borate coating
has high hardness h ≥ 35gpa and friction coefficient of 0.4 ~ 0.6
4. Semiconductor film
Packaging and storage:
It should be sealed and stored in a dry and cool environment, and should not be exposed
to the air, so as to prevent oxidative agglomeration caused by moisture, which will affect
the dispersion performance and use effect.
