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 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 of 2.52g/cm3. Boron carbide has a melting point of 2450

Boron carburide hardness (B4C): Mohs scale 9.3, microhardness 55006700kg/mm2, only second to hardest material Diamond and cubic boron-nitride.

Boron carbide exhibits low density, high strength and high temperature stability, as well as 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 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 56-6200 Kg/mm2, a proportion of 252g/cm3, a melting temperature at 2,250° Celsius.

Chemical properties: resistant to strong 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 alkali or concentrated acidic 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.

What is Boron Carbide how is it produced?

Boron Carbide (B4C) Boride Powder is created by reducing carbon with boron at high temperature in an electric furnace. After grinding the black powder, it is pressed at temperatures above 2,000degC. Its melting temperature is about 2,350degC.

Boron Carbide B4C Powder Uses:

Fine abrasive and advanced materials

It is mainly used in grinding processes for hard materials such a gems or ceramics. Also, it can be used to drill and polish bearings.

Industrial ceramics

The following products are made from boron-carbide powder as a novel material: sandblasting nodes, seal rings, bearings, plungers for mud pumps, pestles and launchers, ceramic coatings, warships, helicopters. It has high melting points, high hardness and high elastic modulus. It also has good wear resistance and self-lubricating qualities.

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

Its high strength and low specific gravity make it ideal for the manufacture of lightweight bulletproof armour, which is used to protect aircrafts, vehicles, ships, and even human bodies.

Improve mechanical part life

Mix boron-carbide powder with metals to create metal-based powder. The original mechanical components are more resistant to wear after special surface treatments.

Special absorber provides energy

The solid fuel rocket uses boron carbide (also known as black gold) as an energy source.

Chemical additives

Because of its high chemical potential and stable chemical properties, it is widely used for the production other boron containing materials such as zirconium and titanium borides.

Advanced refractories

It is widely used to make steel stoves, kiln furniture, and other metallurgical products.

Storage condition of Boron Carbide powder B4C:

B4C Powder dispersion and use effects will be affected by damp reunion. Therefore, boron carbide B4C 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 packing.

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.
