Abstract

Light scattering by the microstructure defects of transparent ceramics causes losses of light and has an effect on the transmission properties. Effects of pores on transmission were studied using the Mie theory. The in line transmissions of transparent magnesium aluminate spinel were calculated as a function of wavelength, pore size, width of distribution and porosity. The results show that the in line transmi ssion gradually increases with an increase in wavelength. Porosity has great impact as the transmission decreases with the increasing of porosity. The minimum of the transmissions were observed when the pore size close to the optical wavelength. Furthermor e, it should be noted that the in line transmission increases with decreasing of the width in pore size distribution in the visible part of the spectrum..
