Rheological Properties of Typical Ceramic Slurries Used in the Lost Wax Technology

Abstract

The results of investigations of the rheological properties of typical ceramic slurries used in the investment casting technology - the lost wax technology are presented in the paper. Flow curves in the wide range of shear velocity were made. Moreover, viscosity of ceramic slurries depending on shearing stresses was specified. Tests were performed under conditions of three different temperatures 25, 30 and 35°C, which are typical and important in the viewpoint of making ceramic slurries in the investment casting technology.
