Abstract
Mix which comprises a) one or more very finely divided silicon dioxide powders having an average particle diameter of from 2 to 100 nm and a BET surface area of at least 30 m2/g, b) one or more particulate components selected from the group consisting of oxides, carbides and nitrides, in each case having an average particle diameter of from >0.5 μm to 30 mm, c) one or more synthetic resins as binders and d) one or more metallic antioxidants having an average particle diameter of from >0.5 to 250 μm. Process for producing a shaped body, in which to the mix is introduced into a mould, pressed if appropriate and heated to a temperature at which the synthetic resin crosslinks thermally. Shaped body which can be obtained therefrom. Process for producing a refractory shaped body, in which the shaped body is carbonized. Refractory shaped body which can be obtained therefrom.
