Armour Ultralight Boron Carbide PlatesAbout
Ceramics based on boron carbide are remarkable for their low density (weight per unit volume) and elevated hardness as compared to other ceramic and non-ceramic materials. For example it weighs 40 to 50 less than Alumina (Al2O3) and 3 times less than various armor steels while being 2 times harder than Alumia and 5 times harder than steel.
