The pore size distributions of alumina and magnesia ceramics were determined by measuring the directional-hemispherical transmittance and reflectance. These values are highly sensitive to changes of the pore structure. The partially sintered alumina

The thermal conductivity of pyrogenic silica pcwder boards mixed with a silicon carbide opacifier is measured as a function of gas pressure and of temperature. At room temperature and gas pressures around 1 to 5 mbar the thermal conductivity is about

Computer simulations of switchable thermal insulation (STI) for solar heating of building facades have been performed. This technique uses a metal hydride to change the H 2 gas pressure within an evacuable panel and thus the thermal conductivity by a

Light scattering by pore/particle interfaces causes diffuse light propagation in ceramics. The diffuse light transmission is highly sensitive to structural changes in the last sintering state. The transmission increases more than one order of magnitu

In order to optimize the infrared extinction of a SiC-powder in a silica powder matrix, Mie scattering calculations for spherical SiC-particles have been performed. A single oscillator-model was applied to calculate the optical constants of SiC. Taki
