Abstract:

This report summarizes the results of a one-year research program devoted to an investigation of the effect of compositional and microstructural variables on the thermal conductivitydiffusivity of engineering ceramics. Particular emphasis was placed on studies of thermal transport phenomena in composite materials. A total of six completed studies have resulted during this program, with another four in progress, as follows 1 Effect of Crystallization on the Thermal Diffusivity of a Cordierite Glass-Ceramic. 2 Thermal Diffusivity of BaMicaAlumina Composites. 3 Thermal Diffusivity of Al2O3 with Dispersed Monoclinic and Tetragonal ZrO2 particles. 4 Effect of thermal Expansion Mismatch on the Thermal Diffusivity of Glass-Ni Composites. 5 Simple Laser Pulse Calorimeter. 6 Thermal DiffusivityConductivity of Dense MagnesiaMagnesia-Alumina Spinel Ceramic. 7 Thermal Diffusivity of Al2O3SiC Composites. 8 Thermal Diffusivity of MgOSiC Composites. 9 Thermal Diffusivity of Al2O3TiC Composites. 10 Thermal Diffusivity of a Partially Electronic Conducting Ceramic Yttrium Chromites.
