La description

Products application Used as abrasives, grinding tools and to manufacture other borides. Used as classic refractory and specific welding material The grain can reinforce metal and non-metal materials Widely used in machinery, electronics, instrumentation, chemical, metallurgy, national defense , aviation and nuclear industry Can indirectly used in semiconductor area with doped boron. It is raw materials of BCL3. Used as high-grade aircraft and human protection material. Product Features Low density ( Its theoretical density is only2.*2**0³kg/m³) High hardness (Mohs' hardness is 9.*6 . It’s a kind of super-hard material whose hardness is only after natural diamond and cubic boron nitride. High melting point（***0℃） Excellent abrasion resistance Large neutron absorbing cross section
