Abstract

In the manufacture of ceramic molds starting from aqueous suspensions, the combination of products already known in the field of ceramic molds (although not bound to the production of unidirectional and single crystal metal components), together with a particular coating sequence and with particular drying and sintering proceedings, allows one to considerably reduce the overall manufacturing time, in particular the drying time, as well as to improve the quality of the castings.
