Boron oxyfluoride glasses in the BOF system: new polymeric spaghetti-type glasses

Direct reaction at T = 200°C of gaseous BF 3 on B 2O 3 in a closed silica tube leads to BOF glass formation in the cold part of the vessel. The vitreous material obtained from vapour phase condensation has a weak dimensionality as indicated by the low glass transition temperature, T g = 60°C. The...

Description
Summary:Direct reaction at T = 200°C of gaseous BF 3 on B 2O 3 in a closed silica tube leads to BOF glass formation in the cold part of the vessel. The vitreous material obtained from vapour phase condensation has a weak dimensionality as indicated by the low glass transition temperature, T g = 60°C. The relationship between the trimeric molecular form, B 3O 3F 3, and the polymer glass (BOF) n is discussed with respect to formation conditions and glass decomposition.
