摘要：

The acquisition of thermal property data for the subsequent computer modelling of solidification-induced defects in the injection moulding of ceramic suspensions is described. Thermal diffusivity of a polystyrene-zirconia suspension was measured between 80 and 160-degrees-C. Volume thermal expansion and specific heat were als recorded as a function of temperature and the equation of state was derived. All the experiments use standard laboratory equipment making the procedure widely applicable. In subsequent work, these data will be used to predict the origin of voids and cracks in ceramic moulded bodies.
