Zusammenfassung:The invention relates to a material mixture for producing casting moulds for machining metal, to a method for producing casting moulds, and to a method which produces said casting moulds and to the use thereof. A fire-resistant moulding base material and a binding agent based on water glass is used in the production of casting moulds. A proportion of the particle-shaped metal oxide is added to the binding agent, said metal oxide being selected from the group of silicon dioxide, aluminium oxide, titanium oxide and zinc oxide. Synthetic amorphous silicon dioxide is preferably used as a metal oxide.
