摘要： The invention relates to a mould material mixture for producing casting moulds for metal processing, a process for producing casting moulds, casting moulds which can be obtained by the process and their use. The production of the casting moulds is carried out using a refractory base moulding material and a binder based on water glass. A proportion of a particulate metal oxide selected from the group consisting of silicon dioxide, aluminium oxide, titanium oxide and zinc oxide is added to the binder, with particular preference being given to using synthetic amorphous silicon dioxide. The mould material mixture contains a surface-active material as further significant constituent. The addition of the surface-active material enables the flowability of the mould material mixture to be improved, which makes it possible to produce casting moulds having a very complicated geometry.
