"PAD" (Pressure Assisted Densification) Boron
Carbide is characterized by outstanding hardness, low specific gravity,
excellent corrosion resistance and a high neutron absorbing cross-section. This
material is suitable for light weight armor, nuclear
and wear applications.
ADVANCED CERAMICS can manufacture
sizes up to 20"x20". The charts to the left list typical
properties.
