Temperature effect (300-1500 K) on the infrared photon transport inside an X-ray microtomographic reconstructed porous silica glass

A Monte Carlo Ray Tracing program has been developed to predict the thermal radiative properties of an X-ray microtomographic reconstructed silica glass containing gas bubbles, for a large domain of wavelength (1-25 μm) and for a large domain of temperature (300-1500 K). The main input of the program is the complex optical index of the corresponding homogeneous silica glass. Validity of the model is checked by comparing a simulated normal spectral emittance, obtained on the reconstructed glass, with the experimental one recorded at T=1300K.
