Boron Carbide has been described as one of the hardest known materials. It is resistant to hot hydrogen fluoride, nitric acid and is therefore not susceptible to these chemicals. It is soluble in molten acid, but insoluble in water or acid.

B4C powder MF: B4C

B4C powder CAS No: 12069-32-8

B4C powder EINECS No: 235-111-5

B4C powder Appearance: Grey black powder

The size of the B4C powder particle can be modified to suit your specific requirements.

Boron Carbide Properties:

Boron carbide’s formula is B4C. The Boron carbide crystal structure is hexagonal. Boron carbonide density = 2.52g/cm3. Boron carbide melt point is 2450

Boron Carbide hardness: The Mohs hardness for B4C material Mohs material Mohs material is 9.3 with a microhardness of 55006700kg/mm2, which is second only to the hard material Diamond and cubic Boron Nitride.

Boron carbide features low density, good strength, high temperatures stability, and chemical stability. Boron carbide is widely used as a wear-resistant material, in ceramic reinforcing layers, in particular in lightweight and boron caride armor. It also has the ability to absorb neutrons.

It is also easier to produce than cubic boron oxide and diamond, making it more popular. You can use it to replace diamonds at certain places.

HTML4C powder is high in purity with small particles size distribution. The B4C material is synthetic ultra stiff materials. It has a hardness of 9.46 and a microhardness of 56-6200Kg/mm2.

The chemical properties of boron carbide are non-magnetic. They can withstand high and low temperatures as well as strong acids, alkalis, and other extremes. In addition to being able to absorb neutrons, it does not emit gamma-rays which are dangerous for the human body.

Boron carbide is an acid that is extremely stable. This means it can be used in concentrated and dilute acid solutions as well as alkali aqueous solutions. Boron carbonide can be kept at a temperature of 800°C for most part in an ambient air. Boron oxide is formed at higher temperatures by its oxidation. This causes it to lose its stability and then oxidize to carbon dioxide and/or boron trioxide.

Boron Carbide Boride Powder produced HTML3_ HTML4C

Boron Carbide Boride Powder B4C is created by mixing boron and carbon at very high temperatures using an electric furnace. Once the powder has been ground, it is pressed at temperatures of over 2,000°C (3.630°F). Its melting temperature is around 2,350degC (4.260degF).

Boron Carbide B4C Powder: Other Sizes

Boron Carbide B4C Powder Uses:

High-quality and sophisticated abrasive material

Due to its excellent grinding performance, boron carbide is used primarily in grinding of materials. This includes: Grinding, drilling, polishing and grinding of hard materials (e.g. gems, ceramics or knives), bearings and cemented carbides.

Industries ceramic materials

Boron carbide powder products include sealing rings and nozzles. Bearings, seals, bearings and plungers of rocket launchers. Also ceramic coatings for warships and helicopters are made with it. The material has high melting points and hardnesses, high elastic modulus and strong wear resistance. This makes it a popular choice for sandblasting, electronics and information technology, as well as other industrial applications.

Materials for control and protection in the nuclear industry

Boron carbide material is highly recommended because of its high thermal neutron capture and neutron absorption. It can also be used as an international shielding material or nuclear reactor control material.

Bulletproof armor

Because of its strength and low specific gravity it’s ideal for light bulletproof armor. It can protect aircraft, boats, and even human beings.

Enhance the mechanical part’s life

Combining boron-carbide powder and metal will produce a metal-based alloy powder. This material has been treated with special surfaces to make the original mechanical parts more resistant to wear, corrosion and acid/alkali resistance.

Special absorber provides energy

Boron carbide (also known as “black Gold”) is used to provide power in the form of a powdered fuel or solid fuel for rockets.

Chemical industry additives

Because of its chemical stability, boron caride doesn’t react with acids and alkali solutions. Also, it has a high potential for chemical reaction, making it a popular material in other boron-containing materials like titanium boride or zirconium borid.

High-quality refractories

Boron carbide’s anti-oxidation properties and resistance to high temperature are reasons why it is used widely in different fields of metalurgisty such as steel stoves, and kiln furniture.

Storage condition of Boron Carbide powder B4C:

B4C powder dispersion performance will be affected and the use of B4C should not be compromised by damp reunion. Boron carbide B4C Powder must be kept dry and in vacuum packed. Additionally, boron carbonide B4C powder must be kept away from stress.

Shipping and Packing of Boron Carbide Powder B4C powder:

Many types of packaging are available depending on the amount of boron carbonide B4C powder.

Boron carbide B4C powder packing – vacuum packing, 100g to 500g or 1kg/bag at 25kg/barrel. Or as you request.

Boron carbide Powder Shipping: Could be sent by sea or air as soon after receipt of payment.
