Temperature and porosity dependence of the elastic constants and thermal conductivity of ceramic refractory phases and refractories
Original language description
Elastic constants, in particular Young's modulus, are basic parameters governing the mechanical behavior of refractories from room temperature up to temperatures where inelastic effects become dominant. In a similar way, thermal conductivity is the key material property determining steady-state heat transfer in refractories unless radiative or convective heat transfer mechanisms come into play. Both types of properties are strongly dependent on the microstructure (in particular porosity) and often quitesensitive to temperature changes. Moreover, the two properties in combination, together with the coefficients of thermal expansion, and other - microstructure-independent - quantities such as specific heat, determine the thermal shock behavior (thermalshock parameters). Therefore, reliable estimates of these quantities are urgently needed in all fields of application of refractories. The present contribution gives an overview of recent theoretical achievements (empirical averages, pred
