Abstract
The invention relates to a glass ceramic armour material consisting (in % by weight in relation to oxide base) of 5-33 SiO, 20-50 AlO, 5-40 MgO, 0-15 BO, 0.1-30 YO, LnO, AsO, NbOand/or ScOand 0-10 PO. The inventive armour material can also be reinforced with inorganic reinforcing fibres in a quantity of 5-65% by weight, preferably consisting of C, SiC, SiN, AlO, ZrOor Sialon. Said armour material is characterised in that it exhibits a high elasticity modulus and is producible from green glass without to fear a premature crystallisation.
