Now our B4C nano powder has beed industrilized used in nuclear industry as Neutron absorbing material and export worldwide. 
boron carbide ceramic powder is one of the hardest materials known. It has the following properties: high purity, small particle diameters with an uniform distribution, low loose loading density, excellent mechanic, thermal, electrical and chemical properties, high abrasion resistance, high surface activity, corrosion resistance, high temperature resistance, low thermal conductivity, high modulus of elasticity. It is ideal for a wide variety of applications. 
Applications 
1) The following devices can be manufactured from it: wear resistance materials, cutting tools, ceramic tooling dies, moulds, horniness alloys, ceramics, wafer slicing machines. 
2) nano boron carbide powder can used in the transparent materials. 
3) New nucleating/refining or sintering agents in metals or alloys or ceramic or plastic for smaller grain size with improved mechanical properties etc 
4) Nuclear: Neutron absorbing products for nuclear technology.
