Optical Constants of Boron Carbide
Abstract
The optical constants n and k have been determined in the 700 - 1200 per cm wavenumber region for a boron carbide flat of compressed 2 micrometer diameter particles by the polarized reflection method. A broad absorption band has been found near 1050 per cm, where k reached values of 1 to 2 and n of lower than 1.5. The scatter of the data points was large, probably because of the demonstrated presence of up to 10% of iron oxide on the surfaces (by SEM/X-ray). More accurate procedures are suggested for future work. The suspension of the particles in one arm of a Michelson interferometer is probably the most direct and superior method for obtaining n and k for such particles.
