Boron Carbide Powder Boron caride powder It is shiny, hard, and black. It is harder than silicon carbide, but less hard than industrial diamond. Boron carbide is more fragile than most pottery. It has a strong chemical resistance and a large cross-section for thermal neutron capture. It is unaffected by hot hydrogen fluoride, nitric acid and other acids. It is soluble and insoluble when it comes into contact with molten alkali. Its relative density (D204), ranges from 2.508 to 2.512. The melting point is 2350. The boiling point of water is 3500

Boron Carbide powder’s physical and chemical properties
Boron carbide It does not react with acid or alkali solutions and has high potential chemically. It is capable of neutron absorption, wear resistance, and semiconductor conductivity. It is one of most stable compounds to acids. It is stable in all concentrated, dilute acid and alkaline water solutions. Boron carbide remains stable in air temperatures below 800F.
Some transition metals and their carbide coexist to create special stability. The metal borides are formed when the transition metals iv to v in the periodic table react strongly at 1000 1100 with boron carbide. It has been reported that boron carbide reacts with transition metal oxides at higher temperatures to form corresponding forms of boron nutride and borides. These borides are mostly rare earth and alkaline-earth metal hexaborides.
It is approximately 9.5 Mohs Hardness, making it the third hardest known substance after diamonds and cubic boron Nitride. Silicon carbide is even harder.
Because of the way it is prepared, boron carbonide is very easy to form carbon defect. This can result in a wide variety of boron/carbon ratio changes that do not affect the crystal structure. This can often lead to the loss of its physical and chemical characteristics. These defects can’t be solved by powder diffraction and require energy loss spectrum and chemical titration.

Boron Carbide Powder
Boron carbonide is ideal for hard materials such as ceramic wear parts like wear plate, pump and bearing parts, faucet, nozzle, valve, parts engineering ceramics and light body armor materials. Specifically,
1. Useful for controlling nuclear fission. Boron carbide absorbs large amounts of neutrons in a non-radioactive manner, making it a great neutron absorber for nuclear power plants.
2. As abrasive materials. Boron carbide has been used for many years as a coarse abrasive. Boron carbide is hard to mold into artifacts due to its high melting point. However, if it is melted at high temperatures it can be made into simple shapes. This is useful for grinding, drilling, polishing, and sandblasting of precious stones and hard alloys.
3. For coating coatings. Boron carbide is also a suitable ceramic coating for warships, and helicopters. It is light and resistant to armor-piercing bullets.
4. It is used to make the nozzle. It is used in the manufacture of gun nozzles. Boron carbide is very hard and wear-resistant. It does not react to acid or alkali. The boron nitride sandblasting tool nozzle is gradually replacing the carbide/tungsten steel, silicon carbide, silicon trioxide and alumina sandblasting tools.
5. Others. Boron carbide is also used for the production of metal borides as well as the smelting and alloying of sodium boron and boron alloys and special welding.
