Formation of borophosphate glass structure within the system BaO-B sub 2 O sub 3 -P sub 2 O sub 5

Formation of borophosphate glass structure within the system BaO-B sub 2 O sub 3 -P sub 2 O sub 5

Formation of distinct crystalline phases during glass synthesis in the system BaO-B72O sub 3 -xP sub 2 O sub 5 (x=0- 60 mol%) is predicted thermodynamically and verified by measured Raman spectra. Initial reaction temp. is reduced by 200- 300 degrees C on addition of P sub 2 O sub 5 to BaO-B sub 2 O...

Zusammenfassung:Formation of distinct crystalline phases during glass synthesis in the system BaO-B72O sub 3 -xP sub 2 O sub 5 (x=0- 60 mol%) is predicted thermodynamically and verified by measured Raman spectra. Initial reaction temp. is reduced by 200- 300 degrees C on addition of P sub 2 O sub 5 to BaO-B sub 2 O sub 3 , with the primary reaction product being BPO sub 4 . 33 refs.
