METHOD FOR DRYING OXIDE GLASSES

摘要

METHOD FOR DRYING OXIDE GLASSES An oxide glass is dried by passing through a melt of the glass a perhalogenated compound including fluorine atoms. For example, C3F8 (e.g. after pre-cracking) can be used to reduce the OH content of a borosilicate glass, and the loss of an optical fibre drawn from such a glass, to low levels.
