Summary:Optimisation of the firing process for high voltage porcelain insulators necessitates knowledge of the properties of the porcelain body and the processes occurring during rapid firing. Thermal conductivity of sintered porcelain has been extensively studied, but data of conductivity during firing are not available. Thermal conductivity of a porcelain body was determined experimentally during firing in the range 100-1350 C. Measurements were carried out by the 'hot wire' method using a Netzsch tester. Thermal conductivity values were calculated and plotted over this range for bodies from two different plants. It was possible to interpret the processes occurring during firing quite reliably and hence to optimise firing regimes. 2 refs.
