Boron Carbide has the highest hardness of any material. It is unaffected by hot hydrogen Fluoride, nor nitric Acid. Insoluble in water or acid, soluble in molten sodium alkali.

B4C powder MF: B4C

B4C powder CAS No: 12069-32-8

B4C powder EINECS No: 235-111-5

B4C powder Appearance: Grey black powder

B4C powder particle size: Can customized according to requirements.

Boron Carbide Properties:
Boron carbide has the formula B4C. Boron carbide crystals are hexagonal. Boron carburide density comes in at 2.52g/cm3. Boron carbide has a melting point of 2450

Boron carburide hardness (B4C): Mohs scale 9.3; microhardness 55006700kg/mm2. Second only to hardest material Diamond and cubic Boron Nitride.

Boron carbide has low density, high strength and high temperature stability. It also has good chemical stability. Boron carbide is widely used as a ceramic reinforcement phase, in particular in lightweight armor and reactor neutron absorbers.

ceramic boron carbide has a lower cost and is easier to manufacture than diamond or cubic boron. It is used more often. It can be used to replace expensive diamonds at certain places, and is also commonly used in drilling, grinding and other aspects.

B4C powder is high-purity, has small particle sizes, and high specific surfaces. B4C, on the other hand, is an ultra-rigid material, with a hardness of 9.46. It also has microhardnesses between 56-6200Kg/mm2, a proportion of 252 g/cm3, and melting temperatures up to 2,250 degrees Celsius.
Chemical properties - non-magnetic and resistant to acids, alkalis, and high and low temperature. It can also absorb neutrons and emit gamma-rays, which are harmful to human health.

Boron carbide is a very stable substance in acid and alkali aqueous solution. Boron carbide remains stable in an atmosphere below 800degC. The boron oxidation product is lost to the gas phase and leads to its instabilities and oxidation into carbon dioxide and Boron trioxide.

How does Boron Carbide B4C Boride Powder get produced?
Boron Carbide (B4C) Boride Powder is created by reducing carbon with boron at high temperatures using an electric furnace. After grinding the black powder, it is solidified through pressing at temperatures above 2,000degC. Its melting temperature is about 2,350degC.

Boron Carbide B4C Powder Uses:

Fine and Advanced Abrasive Materials
It is used in grinding processes for hard materials such a gems or ceramics. Also, for cutting and polishing knives, bearings and cemented carbide.
Industrial ceramics
The following products are made from boron-carbide powder as a novel material: sandblasting nodes, seal rings, nozzles bearings plungers for mud pumps pestles rocket launchers ceramic coatings warships helicopters etc. It has high melting points, high hardness and high elastic modulus. It also has good wear resistance.
Materials for shielding and controlling the nuclear industry
Boron carbide is a highly regarded material that has been internationally recognized for its neutron absorption properties, thermal neutron capture, and radiation resistance.
Bulletproof armor
Due to its strength and low specific gravity, it's especially suitable for use as lightweight bulletproof armour, such a protecting aircraft, ships, vehicles and human body.
Improve mechanical part life
Mix boron-carbide powder with metals to create metal-based powder. After a special treatment, original mechanical components are more resistant to corrosion and wear.
Special absorber provides energy
The solid fuel rocket uses a powdered form of boron carbide (also known as "black-gold") as its power source.
Chemical additives
Because of its high chemical potential and stable chemical properties, it is widely used for the production other boron-containing material, such as titanium boride or zirconium.
Advanced refractories
It is widely used for steel stoves and kilns furniture because of its antioxidation and resistance to high temperatures.

Storage condition of Boron Carbide powder B4C:
B4C Powder dispersion and use effects will be affected by damp reunion. Therefore, the B4C boron powder must be packed in vacuum and kept in a dry and cool room. The boron carbide powder should not be exposed to stress.

Shipping & Packing of Boron Carbide (B4C) powder:
The amount of B4C powder we use will determine the type of packaging.
Boron carbide powder packaging: vacuum packed, 100g,500g or 1kg/bag; 25kg/barrel.
Boron carbide B4C Powder Shipping: Could be shipped by sea, air, or by express as soon after payment receipt.
