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 scale 9.3, and microhardness 55006700kg/mm2, which is only second to hardest material Diamond and cubic boron-nitride.
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 and drilling.
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, a melting point 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 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.
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. The powdered black is pressed at temperatures above 2,000degC to solidify it. Its melting temperature is about 2,350degC.

Boron Carbide B4C Powder Uses:
Fine and advanced abrasive materials
Because of the high grinding efficiency of boron carbide, it is mainly used as a grinding medium in the grinding process of materials, such as: grinding, grinding, drilling and polishing of hard materials such as gems, ceramics, knives, bearings, and cemented carbides.
Industrial ceramic materials
Products made of boron carbide powder: sandblasting nozzles, sealing rings, nozzles, bearings, plungers of mud pumps, pestles and rocket launchers, ceramic coatings for warships, helicopters, etc., as a new type of material. It has the characteristics of high melting point, high hardness, high elastic modulus, strong wear resistance, and good self-lubricating properties and is widely used in sandblasting machinery, electronics, information, aerospace, automobile and other industries.
Shielding and control materials for the nuclear industry
Boron carbide material has a large thermal neutron capture section, excellent neutron absorption and radiation resistance, and is internationally recognized and recommended as a nuclear reactor control material and shielding material.
Due to its high strength and small specific gravity, it is especially suitable for use in lightweight bulletproof armor, such as the protection of aircraft, vehicles, ships and human bodies.
Improve the life of mechanical parts
Combine boron carbide powder with metal to produce metal-based alloy powder. After special surface treatment of this material, the original mechanical parts are more resistant to wear and corrosion resistance to acid and alkali.
Special absorber provides energy
Boron carbide, also known as “black gold”, is used as a power source in powder form as a solid fuel for the rocket.
Chemical industry additives
Due to its stable chemical properties, boron carbide does not react with acid and alkali solutions and has a high chemical potential, so it is widely used in the production of other boron-containing materials, such as zirconium boride and titanium boride.
Because of its anti-oxidation and high-temperature resistance, boron carbide is used as a high-grade shaped and unshaped refractory material and is widely used in various fields of metallurgy, such as steel stoves and kiln furniture.
Storage Condition of Boron Carbide B4C powder:
Damp reunion will affect B4C powder dispersion performance and using effects, therefore, boron carbide B4C powder should be sealed in vacuum packing and stored in cool and dry room, the boron carbide B4C powder can not be exposure to air.
