MOULD MATERIAL MIXTURES ON THE BASIS OF INORGANIC BINDERS, AND METHOD FOR PRODUCING MOULDS AND CORES FOR METAL CASTING

摘要

The invention relates to mould material mixtures on the basis of inorganic binders, for producing moulds and cores for metal casting. Said mixtures consist of at least one refractory mould base material, an inorganic binder and amorphous silicon dioxide as an additive. The invention also relates to a method for producing moulds and cores using said mould material mixtures.
