Abstract
Methaphsophate glass was synthesized by melting a mixture of analytical grade Na-hexametaphosphate, Al-metaphosphate and silver as silver nitrate. The thermal and structural changes in the courses of synthesis were investigated by DTA and IR structural analysis. The characteristic temperatures of glass transformation and softening were found to be 477°C and 522°C, respectively. The glass was characterized by measuring its thermal expansion coefficient, index of refraction and optical density. The glass was found to be transparent in the VIS spectral region. The structure of the synthesized glass corresponded to a mixture of linear polyphosphates and cyclic metaphosphates.
