The coordination state of B and Al of borosilicate glass by IR spectra

The IR spectra of R 2 O-RO-B 2 O 3 -SiO 2 and R 2 O-RO-B 2 O 3 -Al 2 O 3 -SiO 2 glasses were tested for the study of coordination state of B, Al and their content. The results show that no matter Na 2 O/B 2 O 3 >1, =1, or<1, both [BO 3 ] and destroyed Si-O bond exist in glass structure; the ad...

Summary:The IR spectra of R 2 O-RO-B 2 O 3 -SiO 2 and R 2 O-RO-B 2 O 3 -Al 2 O 3 -SiO 2 glasses were tested for the study of coordination state of B, Al and their content. The results show that no matter Na 2 O/B 2 O 3 >1, =1, or<1, both [BO 3 ] and destroyed Si-O bond exist in glass structure; the addition of Al 2 O 3 to borosilicate glass reduced both the number of non-bridging oxygen in the silicate network and the number of [BO 4 ] units.
