Physical Properties of Ternary NaPO3-KHSO4-MX (M=Na, K and X=Cl, Br) Glasses

Abstract : This contribution focusses on some thermal, optical and mechanical properties of sulfophosphate glasses containing MX (M=Na, K and X=Cl, Br) synthesized in the NaPO3- KHSO4- MX systems. The synthesized samples of 1 cm in thickness present large vitreous areas. These glasses are stable at room atmosphere and soluble in water. Characteristic temperatures of glass transition and onset of crystallization were measured. The temperature of glass transition and the coefficient of thermal expansion range between 180 and 254 °C and between 217.10-7 k-1 and 270.10-7k-1, respectively. Refractive index of all the samples is found is close to 1.48 in the 633-1555 nm wavelength range. The micro hardness and the elastic moduli of the samples were also measured
