"PAD" (Pressure Assisted Densification) Titanium Diboride
(TiB2) is an electrically conductive, refractory hard material having
excellent corrosive resistance to molten alumina. It has applications for armor and as sputtering targets.
ADVANCED CERAMICS can manufacture
sizes up to 20"x20". The charts to the left list typical
properties.
