Abstract (en)
[origin: WO2010034762A2] The invention relates to a method for producing a casting mould for casting highly reactive melts, in particular for casting titanium, titanium alloys or intermetallic titanium aluminides. Said method consists of the following steps: a contact layer (1) is produced by applying a first slicker containing a first Y2O3-powder as an essentially solid component, to a mould core, the contact layer (1) formed from the first slicker is sanded with a second Y2O3-powder containing Y2O3 as the essential component. With respect to a particular efficient process, a first dry mass for producing the first slicker contains at least 75 wt.% Y2O3 and as additional solid components, at least 1.0 - 25 wt.% of a hydraulic binder.
