摘要：

A synthesis of alkali-free borosilicate gel from Si(OEt)(4) and (MeO)(3)B3O3 in non-aqueous solvents is reported; the formation of the gel proceeds via rapid transesterification/oxygen transfer with elimination of B(OR)(3); removal of volatiles from the gel, followed by drying (60 degrees C, 12 h) and furnacing in air (600 degrees C, 20 min) resulted in alkali-free borosilicate glass.
