Patent ID: 8303702

Claim:
A preparation for producing refractory materials, comprising: one or more particulate, refractory components; at least one binder; and 3 to 15% by weight of water; wherein the particulate, refractory component has a mean particle diameter of greater than 0.3 μm and the at least one binder comprises: from 0.05 to 50% by weight of a very fine particulate binder having a mean particle diameter of from 10 nm to 0.3 μm, selected from the group consisting of a pyrogenic aluminum oxide, a pyrogenic titanium dioxide, a pyrogenic zirconium dioxide and mixed oxides thereof, from 0 to 20% by weight of an inorganic binder, from 0 to 20% by weight of a hydraulically setting binder, and from 0 to 15% by weight of an organic, silicon-free binder, where the proportion of the particulate, refractory component is equal to 100 and the percentages of the additional materials in the preparation are based on the particulate component.
