Viscous flow and MOS properties of MgF2?B2O3?GeO2?SiO2 glasses with ionic bonds

Removal of OH Absorption Bands Due to Pyrohydrolysis Reactions in Fluoride-Containing Borosilicate Glasses

“…Infrared transmission spectra were measured using a Digi-Laboratory spectrophotometer with 10;20;1 mm plates. Glass flow points were obtained from thermal expansion curves using a method previously described (10,11). Dry air was blown by bubbling through molten glass for 0.5 h during melting, using a platinum tube.…”
