Thermal Conductivity and Diffusivity of Engineering Ceramics.

Abstract

This report summarizes the results of a two-year research program devoted to an investigation of the effect of compositional and microstructural variables on the thermal conductivity/diffusivity and its temperature dependence of structural ceramics. A total of twelve completed studies have resulted from this program, as follows: (1) Effect of Temperature Dependence of Thermal Conductivity on Thermal Stress Resistance of Brittle Materials, In Particular Aluminum Oxide; (2) Effect of Matrix Conductivity on Radiation Heat Transfer Across Pores; (3) The Thermal Diffusivity of Al2O3-Cr2O3 Solid Solutions; (4) Effect of Micro-cracking on the Thermal Diffusivity of Fe2TiO5; (5) Role of Thermal Diffusivity in the Performance of Ceramic Oxide Cutting-Tool Materials; (6) Thermal Diffusivity of Non-Stoichiometric Titanium-Dioxide; (7) Thermal Diffusivity of Si-Al-O-N Compositions; (8) Thermal Diffusivity of Glassy Carbons; (9) Effect of Micro-cracking on the Thermal Diffusivity of Polycrystalline Aluminum-Niobate; (10) Effect of Micro-cracking on the Thermal Diffusivity of MgTi2O5; (11) Micro-cracking as a Mechanism for Improving Thermal Shock Resistance and Thermal Insulation Properties of Ceramic Materials; (12) The Effect of Microstructure and Composition on the Thermal Diffusivity of Structural Ceramics.
