Optical parameters of silicon carbide and silicon nitride ceramics in 0.2–1.3 μm spectral range

Abstract

The optical properties—reflectance, absorptance, and transmittance—of silicon carbide (SiC) and silicon nitride (Si3N4) ceramics in the 0.2–1.3 μm spectral range were estimated by means of Monte Carlo simulation using single-crystal macroscopic optical constants assumed to remain uniform over a small unit of ceramic volume. The data obtained are in good agreement with the measurements made by other authors.
