Elastic properties and thermal conductivity of oxide- and silicate-based high-temperature engineering ceramics

Popis výsledku v původním jazyce

Elastic properties and thermal conductivity are among the most important basic properties that must be reliably known not only for assessing the room temperature behavior and insulation capability but also the high-temperature performance and thermal shock resistance of high-temperature engineering ceramics and refractories. This contribution reports on some of our results - theoretical calculations as well as experimental measurements - concerning oxides (alumina, zirconia), two-phase composites (alumina-ziconia) and multiphase silicate-based ceramics (cordierite ceramics as well as kaolin-mullite- and mullite-alumina based ceramics). The dependence of Young's moduli and thermal conductivity on phase composition (volume fractions of solid phases), porosity (volume fractions of pores) and temperature are discussed for these materials. It is shown that the so-called one-point bounds (Wiener-Paul bounds) are generally useful for the estimation of multiphase composites, and that two-phase
