High Hardness Abrasive Materials Boron Carbide Nanopowders
Spec for boron carbide nanopowders:
1. K520-1: 0.5um, 99%
2. K520-2: 1-3um, 99%
Boron carbide performance:
Boron carbide powder is gray and black powder, with
a low density, high strength, high temperature stability and good chemical
stability, wear-resistant materials, ceramic reinforcement, especially for use
in lightweight armor, and other aspects of reactor neutron absorber.
Boron carbide Application:
1. Control of nuclear fission
Boron carbide can absorb large amounts of neutrons without forming
any radioisotope, so it is the most ideal neutron absorber in nuclear power
plant, and is mainly controlled nuclear fission neutron absorber rates. Boron
carbide in nuclear reactor field is mainly to make control rod ,but sometimes
because want to increase the surface area and put it into a powder.
2. Abrasive materials
Boron carbide has been used as a grit abrasive
material in long time ago. Because of its high melting point in itself, is not
easy to cast artifacts, but by high temperature melting powder which can be processed
into a simple shape. Widely used in carbide, precious stones and other hard
materials, grinding, grinding, drilling and polishing.
3. Coating Material
Boron carbide can be as warships and helicopter
ceramic coating, its light weight and the ability to resist the projectile to
penetrate into the overall anti-hot coating layer.
4. nozzle
In the arms industry used to make guns nozzles.
Boron carbide, an extremely hard and wear resistance, high / low temperature,
high pressure, high hardness, wear resistance than with boron carbide
features,, boron carbide nozzles nozzle system will gradually replace the known
carbide / tungsten carbide and steel silicon, silicon nitride, alumina,
zirconia, and other materials of nozzles.
5. Other
Boron carbide is also used in the manufacture of
metal borides and smelting boron, sodium, boron alloys and special welding.
