الوصف: | Effect of B 2 O 3 /P 2 O 5 substitution on the properties and structure of the ternary 67SnO–(33–x)P 2 O 5 –xB 2 O 3 composition line (from x = 0–33 mol%) are examined in this contribution. We show that density and glass transition temperature increase while molar volume and thermal expansion coefficient decrease with increasing B 2 O 3 concentration. Density and thermal properties experience an original three-domain evolution with rapid (region I: 0 ≤ x < 5), substantial (II: 5 < x ≤ 15), and moderate (III: 15 < x ≤ 33) increase. In order to explain this unconventional behaviour, the glass structure has been investigated using high magnetic field 1 dimensional 31 P and 11 B MAS–NMR, micro-Raman and infrared spectroscopies. 11 B MAS–NMR experiments allow to (i) monitor the 3- and 4-fold coordinated borate species proportion and (ii) highlight the presence of unreported 4-fold coordinated species in the region (III). Finally, it is shown that substitution of P 2 O 5 by B 2 O 3 induces an alteration of the dimeric phosphate network and formation of mixed anion structure that consists of Q 0 phosphate units, 3- and 4-fold coordinated borate units and their combinations. |
