Optical and thermal properties of binary calcium phosphate and barium phosphate glasses
Optical and thermal properties of binary calcium phosphate and barium phosphate glasses
Binary calcium phosphate and barium phosphate glasses corresponding to xCaO–(100-x)P2O5 and xBaO–(100-x)P2O5, respectively, have been prepared in the range of 20≤x≤50. Assessment of the optical and thermal properties reveal that refractive index (n) and glass transition temperature (Tg) show a minima while thermal expansion coefficient (α) and thermo-optic coefficient (dn/dT) change monotonically as the amount of modifying oxides, CaO and BaO, increase. α > 9 × 10-6/°C is required for the calcium phosphate and barium phosphate glasses to exhibit negative dn/dT.

Abstract
Binary calcium phosphate and barium phosphate glasses corresponding to xCaO–(100-x)P2O5 and xBaO–(100-x)P2O5, respectively, have been prepared in the range of 20≤x≤50. Assessment of the optical and thermal properties reveal that refractive index (n) and glass transition temperature (Tg) show a minima while thermal expansion coefficient (α) and thermo-optic coefficient (dn/dT) change monotonically as the amount of modifying oxides, CaO and BaO, increase. α > 9 × 10-6/°C is required for the calcium phosphate and barium phosphate glasses to exhibit negative dn/dT.
