Abstract (en)
[origin: WO2006058664A2] The invention relates to the use of liquid glass and/or one or more precursors of the latter during the production of moulds and/or cores used for casting purposes. According to said method, liquid glass, acting as component (1) and/or one or more precursors of the latter and one or more poorly soluble metallic salts, acting as component (2) and/or mixtures of components (1) and (2) are blended with particulate materials that act as component (3) and do not melt during the casting process, in order to produce moulds that can be removed after the casting process and/or cores for casting purposes. The invention also relates to a method for producing corresponding moulds and/or cores, to corresponding moulds and cores, in addition to other inventive embodiments that are covered by the description.
