Nano Boron Carbide Powder ------EltNano-B4C Properties and Characters
1. Nano-boron carbide powder has high purity, small particle size distribution and high specific surface area. 2. Nano-boron melting point can reach high up to 2350 ℃, boiling point ≥ 3500 ℃, hardness is 9.3, flexural strength ≥ 400Mpa; 3. The product can not react with acid and alkali, with high chemical potential, which is one of the most stable substances to acid. and also has good quality of high temperature, high strength, high grinding efficiency, high hardness, high elastic modulus, strong wear-resistance and good self-lubrication; 4. Its ability to absorb neutrons without forming long lived radionuclide makes the material attractive as an absorbent for neutron radiation arising in nuclear power plants. Nuclear applications of boron carbide include shielding, control rod and shut down pellets. Within control rods, boron carbide is often powdered, to increase its surface area.

Application direction: 1. Fine and advanced grinding materials: As a grinding media, it mainly used in the technology of materials grinded into powder, such as the grinding and cutting, grinding, drilling, polishing of precious stones, ceramics, tools, bearings and cemented carbide and other carbides. 2. Materials in ceramic industry: Such as the manufacture of the ceramic coating on the nozzles, sealing rings, effuser, bearings, the plungers and pestles of the mud pump, and rocket launchers, warships and helicopters. 3. Shielding and control materials: The best control and shielding materials of nuclear reactors are the security of nuclear industry. 4. Bullet-proof armor: It should be used in lightweight bullet-proof armor, such as the protection of aircraft, vehicles, ships and body; 5. Be used to manufacture alloy powder and improve the life of mechanical parts.
Storage: Nano Boron Carbide Powder should be stored in a cool, dry and sealed environment, can not be exposure to air to avoid Reunion in the wet condition, affecting the dispersion properties and use effect, in addition, it should avoid the heavy pressure.
