Abstract :
Scattering loss and viscosity against temperature measurements have been carried out on fluoride glasses. The results indicate for the first time a ¿-4 behaviour for scattering loss in the 0.45¿0.75 ¿m wavelength range. Activation energies for viscous flow were found to be similar for both ZrF4¿ and HfF4¿based glasses.
