Structure of Glass Forming Halides. I. Liquid Beryllium Fluoride

摘要: Viscosity and electric conductivity measurements have been made on liquid beryllium fluoride over the temperature range 700–950°C. The high specific resistance viscosity magnitude of corresponding energies activation indicate that classical random network structure for glasses is applicable. Liquid BeF2, similar to GeO2 SiO2, highly associated even at elevated temperatures. At a 200° above melting point, energy viscous flow greater than heat vaporization. ease glass formation attributed liquid.
