Characters are as follows:

`Light Density

`High Hardness and Strength

`Erosion Resistance

`High Modulus of Elasticity

`Neutron Absorber

`Low thermal conductivity

Boron carbide is smelted from boricacidand powdered carbon in electric furnace under high temperature. Dependingonhardness of 4950kgf/ mm2, It is even harder than diamond and cubicboronnitride. Because of their high strength, low density, corrosionresistant, hightemperature resistant, low thermal conductivity, high modulus ofelasticity, it isideal for a wide variety of applications.
