10/3/2008· Abstract: Silicon Carbide (SiC) optical constants are fundamental inputs for radiative transfer models of astrophysical dust environments. However, previously published values contain errors and do not adequately represent the bulk physical properties of the cubic (beta) SiC polytype usually found around carbon stars.

Effect of oxygen atom boardment on the reflectance …
1/4/1993· Chemical-vapor-deposited silicon carbide mirrors were exposed to boardment by 8-km/s oxygen atoms that simulated the effects of exposure in low Earth orbit for periods up to 7.5 yr. The reflectances of four mirrors were measured before and after exposure at five wavelengths (58.4, 73.6, 104.8, 121.6, and 161 nm) and at 11 angles of incidence from 5 degrees to 80 degrees .
