Abstract
A series of sodium borophosphate glasses of the composition (1âx)NaPO3âxB2O3 have been synthesised from Na2CO3, B2O3 and P2O5 and their optical and thermal properties investigated. The results show that refractive index (n) and glass transition temperature (Tg) show a maximum at about B/(B+P)=0.6 while thermal expansion coefficient (α) and thermo-optic coefficient (dn/dT) change monotonically with the B/(B+P) ratio. These observations can be interpreted based on the incorporation of BO3 and BO4 units into the glass structural network.
