Description:
White abrasive material is a high-quality raw material, made of fused refining crystal, high purity, self-sharpening,
good acid and alkali resistance, high temperature, thermal properties and stability it is slightly higher than the corundum hardness, toughness slightly lower, high purity, good self-sharpening,
acid corrosion, high temperature thermal stability. Made with the abrasive, for grinding high-carbon copper, high-speed steel.
Applications:
1 Due to its extreme hardness it has good wear and abrasive resistance then it can be used as not only lapping and polishing material such as the polishing of high speed steel but also cutting tools for hard metal wire drawing dies abrasive tools with high abrasive and wear resistance sealed washer (gasket) and the nozzles for water jet cutters slurry pumping grit blasting etc
2 To take place of diamond in the processing of semiprecious gems such as ruby synthetic corundum etc
3 As the raw material for refractory industry special welding etc
4 To be used as raw material for ballistic Armour and relative products
5 Due to its capability to generate tremendous amount of heat in combination with oxygen boron carbide is used as rocket propellant in aerospace industry
6 It is widely used in nuclear industry for its good absorption of neutron
7 Other using an indispensable material for making Doric metal for example titanium bride Boris steel etc the models and dies of ceramic tools evaporating boat and parts
For perfect hardness and wear resistance Boron Carbide is widely used for lapping, polishing and further processing precious jewel etc
Competitive Advantage:
1 Extreme hardness Moh's hardness 9.36
2 Difficult to sinter to high relative density without the use of sintering aids
3 Good chemical resistance
4 Good nuclear properties
5 High temperature low density resistance gravity: 2.52g/cm3 smelting point: 2450°C
