High Purity Boron Carbide B4c Powder from Coarse to Superfine
Micron Sizes for Different Applications, Great Quality Factory
PriceBoron Carbide Powder (B4C) a black crystal powder, is one of
the hardest Man-Made materials. Its hardness with Mohs hardness
9.36 and microscopic hardness 5400-6300kg/mm2 is only near upon
diamond. Its density is 2.52g/cm3 and melting point is 2450ºC. It
has excellent abrasion resistance and large neutron-absorbing cross
section. The boron carbide possesses properties of endurance hi/low
temperature, no reaction with either acids or alkalis, high
grinding efficiency, no magnetism. It is a good replacement of
diamond. Boron carbide also possesses the special properties of
light quality, neutron absorbing, semi-conductivity, etc., so it is
widely used in machinery, electronics, instrumentation, metallurgy,
national defense, armed forces, nuclear, aviation industry, and
also used as abrasives, classic refractory and specific welding
materials, human protection materials and so on. Boron
carbide is widely applied as follows: boriding refractory, ion
transfusion, film layer as well as grinding, polishing, lapping,
drilling hard metal alloys, sapphire, watches, jewels, etc.
Meanwhile, it is main material for the wear-resisting parts,
precise meter-age element, sandblasting nozzle, precise spray
nozzle, sealed washer, smelting boron steel, boron alloy, etc.
Boron carbide has showed many better properties of physics
and chemistry in the hi-science/technology fields. Physical

Boron Carbide B4C Boron Carbide, molecular formula B4C, is one
of the three hardest materials known (the other two are diamond and
CBN cubic boron nitride) and commonly used in tank armor,
bulletproof clothing, and many industrial products. Boron
Carbide can absorb large amounts of neutrons without forming any
radioactive isotopes, so it's an ideal neutron absorber for nuclear
power plants, and can be used to control the rate of nuclear
fission. Boron Carbide is mainly made as a controlled rod in
a field, but sometimes it is made into the powder to
increase the surface area. It has many advantages including low
density, high strength, high temperature stability and good
chemical stability, widely used in wear resistant parts, ceramic
reinforcement, especially in light armor, reactor neutron
absorbers, etc. In addition, boron carbide is easier to
manufacture and less costly than diamonds and cubic boron
nitride(CBN), so it can be used more widely. It can replace
expensive diamonds in some applications and is commonly used in
grinding, lapping, drilling, etc. Control Nuclear FissionBoron
carbide can absorb large amounts of neutrons without forming any
radioactive isotopes, which makes it an ideal neutron absorber for
nuclear power plants, and neutron absorbers are mainly used to
control the rate of nuclear fission. Boron Carbide is mainly made
as a controlled rod in a field, but sometimes it is
made into the powder to increase the surface area. At Chernobyl
nuclear accident in 1986, Russia eventually stopped the chain
reaction in the reactor after dropping nearly 2,000 tons of boron
carbide and sand. Grinding Polishing Lapping MaterialsBoron
carbide has been used as a coarse abrasive material long
before. Due to its high melting point, it is not easy to cast into
artifacts, but it can be processed into simple shapes by melting
the powder at high temperatures. So it is often used for grinding,
lapping, drilling and polishing hard materials such as hard alloy,
gems and so on. Ceramic CoatingBoron carbide can also be used
as a ceramic coating for warships and helicopters, which is
lightweight and has the ability to resist armor-piercing bullets
penetrating the thermal coating to form a monolithic
shield. Boron Carbide Sandblasting Nozzles with Longer Working
Life Better Wear-resistanceIt can be used to manufacture gun
nozzles in the arms industry. Boron carbide, extremely hard and
wear-resistant, no reaction with acid-base, high/low temperature
resistance, high pressure resistance, crystal system: hexagonal,
density: 2.52g/cm3, Mohs hardness: 9.36, microhardness
5400-6300kg/mm2, bending strength ≥400M
