High Purity Boron Carbide B4C Powder CAS 12069-32-8, 99%

Boron Carbide has the highest hardness of any material. It is unaffected by hot hydrogen Fluoride, nor is it affected by nitric Acid. Insoluble in water or acid, but 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, is 2.52g/cm3. Boron carbide has a melting point of 2450

Boron carburide hardness (B4C): Mohs hardness is 9.3, and its microhardness range is between 55006700kg/mm2, which is only second to the hardest material cubic boron-nitride and diamond.

Boron carbide is known for its high temperature stability, low density and 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 for grinding, drilling, 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 252g/cm3, and melting temperatures at 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 acidic solutions. It is also stable in alkaline or concentrated acidic aqueous solution. Boron carbide remains stable in an atmosphere below 800degC. The boron oxide that is formed when it is oxidized at a high temperature is lost to the gas phase. It then oxidizes into carbon dioxide and boron trioxide.

What is Boron Carbide how is it produced?
Boron Carbide (B4C) Boride Powder is created by reducing carbon with boron at high temperatures using an electric furnace. The powdered black is then pressed at temperatures above 2,000degC. Its melting temperature is about 2,350degC.

Boron Carbide B4C Powder Uses:

Fine and Advanced Abrasive Materials
It is mainly used in grinding processes for hard materials, including gems. ceramics. knives. bearings.
Industrial Ceramic Materials
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 is characterized by a high melting point, a high hardness, elasticity, wear resistance and self-lubricating qualities. It's widely used in the sandblasting industry, electronic, information, aviation, automobile, and other sectors.
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
Especially due to its strength and low specific gravity, lightweight bulletproof armour is ideal for protecting aircraft, vehicles, vessels and even human bodies.
Improve mechanical part life
Mix boron-carbide powder with metals to create metal-based alloys powder. The original mechanical components are more resistant to corrosion and wear after special surface treatments.
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 used widely in 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 high-temperature resistance and antioxidation.

Storage condition of Boron Carbide powder B4C:
B4C Powder dispersion and use effects will be affected by damp reunion. Therefore, the B4C Powder should be packed in vacuum and kept in a dry and cool room. It is also important to avoid putting the boron-carbide B4C powder under 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 air, sea, or express as quickly as possible after payment receipt.
