Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The effects of solid phase thermal conductivity, pore thermal conductivity, and pore volume fraction on the measured effective thermal conductivity of porous ceramics with pore volume fractions of 4 to 95% were investigated. The experimental results were then compared with pre-existing numerical models. It was found that the Maxwell-Eucken relation for closed porosity and the Landauer relation for open porosity were able to closely predict the effective thermal conductivity for tin oxide, ...
