The invention relates to mold material mixtures containing an oxide of aluminum and an oxide of zirconium as particulate mixed metal oxide, in combination with refractory mold base materials and a water glass-based binder system. The mold material mixtures, also in the form of multicomponent systems, are used for the production of molds and cores for the foundry industry.

Molding material mixtures containing metal oxides of aluminum and zirconium in particulate form

The invention relates to mold material mixtures containing at least one aluminum oxide in the alpha phase and/or at least one aluminum/silicon mixed oxide, except for aluminum/silicon mixed oxides having a layered silicate structure, as a particulate metal oxide, in combination with refractory mold base materials and a water glass-based binder system. The mold material mixtures are used for the production of molds and cores for the foundry industry.

Molding material mixtures containing aluminum/silicon oxides in particulate form

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

Mold material mixtures on the basis of inorganic binders, and method for producing molds and cores for metal casting

The invention relates to molding material mixtures containing barium sulfate in combination with refractory basic molding materials and a waterglass-based binder system for producing casting molds and cores for the foundry industry in order to obtain cast pieces, in particular aluminum ones, which have an improved cast surface.

Molding material mixtures containing barium sulfate

The invention relates to molding material mixtures containing a molding base material, water glass, amorphous silicon dioxide and an oxidic boron compound, and the production of molds and cores, in particular for metal casting.
