Abstract
A process is provided for producing carbon free borosilicate glass compositions by hydrolyzing a silicon tetraalkoxide so as to form an at least partially hydrolyzed silicon tetraalkoxide which is then combined with a boron alkoxide and sufficient water to produce a substantially hydrolyzed borosiloxane, or borosilicate precursor, and then this precursor in the presence of free water is fractionally distilled for a time sufficient to remove all alkanol by-product.
