Abstract
Official abstract text for this publication.
The invention relates to a composition (batch) for producing a shaped refractory ceramic product, a method for producing a shaped refractory ceramic product, and a shaped refractory ceramic product.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition for producing a shaped refractory ceramic product comprising: 85 to 99% by mass Y 2 O 3 ; and 1 to 15% by mass ZrSiO 4 ; relative to the total mass of the composition in each case. 2. The composition according to claim 1 , in which the Y 2 O 3 present has a grain size smaller than 4.0 mm. 3. The composition according to claim 1 , in which the ZrSiO 4 present has a grain size smaller than 1.0 mm. 4. The composition according to claim 1 , which contains at least one of the following oxides or the sum of oxides in the maximum proportions indicated in each case: TiO 2 ≦0.15% by mass; Fe 2 O 3 ≦0.15% by mass; Na 2 O+K 2 O≦0.15% by mass; CaO+MgO+BaO≦0.20% by mass; relative to the total mass of the composition in each case. 5. A method for producing a shaped refractory ceramic product from a composition, which method comprises the following steps: providing a composition, the composition comprising: 85 to 99% by mass Y 2 O 3 ; and 1 to 15% by mass ZrSiO 4 , relative to the total mass of the composition in each case; mixing the composition with a binder; moulding the composition mixed with a binder into a shaped body; and firing the shaped body to form a shaped refractory ceramic product.
