Abstract
The refractive index and absorption coefficient of amorphous Fe2O3-SiO2-CaO-Al2O3 slags have been determined at room temperature as functions of the basicity of [mass pct CaO]/[mass pct SiO2] and the Fe2O3 concentration. The refractive index has been measured by an ellipsometer at 546 nm, and the absorption coefficient has been determined from transmittance measured by a spectrophotometer in the wavelength range of 350 to 1000 nm. The refractive index increases with increasing basicity of [CaO]/[SiO2] and the Fe2O3 concentration. On the other hand, with decreasing basicity of [CaO]/[SiO2], the absorption coefficient is increased in the near-infrared region, and the absorption edge by the charge transfer band is shifted to a shorter wavelength. With increasing Fe2O3 concentration, the absorption coefficient is increased in the measured wavelength range, and the absorption edge by the charge transfer band is shifted to a longer wavelength. These dependences of refractive index and absorption coefficient on the basicity and the Fe2O3 concentration are discussed.
