Boron Carbide / Silicon carbide NIJ III Bulletproof Ballistic Armour Plates
Applications:
Application of B4C in National Defence Industry:B4C is the material of bulletproof products ,such as bulletproof plate/vests,ceramic bulletproof tile in military airplane
pilot cabin,and modern armored personnel vehicle and tank,can bring obvious economic returns and military benefits .
Application of B4C in Nuclear Industry:
B4C can be prepared into controlling bars,adjusting bars,accident bars,safety bars,screen bars,radiation resistant
B4C tilts,plates or neutron absorber,andradiation resistant layer for atomic reactor together with cement which is the most important functional
competent only next to reactor fuel.
Application of B4C in Refractory Industry:
B4C can be used as antioxidation agent for low Carbon magnesia carbon bricks and castables. It can be applied in key positions which suffer from serious erosion and high
temperature,such as ladle, taphole(nozzle),sliding plates,and stopper.
