摘要

Two industrial process schemes were employed to produce KS-4V and KI grade glasses from synthetic amorphous silica (SAS) and natural quartz, respectively. A comparison of the optical characteristics of the resulting glasses in the ultraviolet (UV) spectral region showed that glasses melted from SAS exhibit higher transparency and greater transmittance within the 190 – 1000 nm wavelength range. The difference in light transmittance coefficients is attributed to both the specific features of the melting processes and the presence of trace elements in raw materials.
