Glasses in the 2TeO,xNa,O( 1 -x)V,O, system have been synthesized for 0 5 x 5 1. Glass transition temperatures are between 220°C and 250°C. Conductivity data obey an Arrhenius type behaviour for temperatures ranging from room temperature to below their glass transition temperatures. Values of activa
Conditions of glass formation in the \(\mathrm{Na}_{2} \mathrm{O}-\mathrm{TiO}_{2}-\mathrm{P}_{2} \mathrm{O}_{5}\) system are reported. The largest quantity of \(\mathrm{TiO}_{2}\) which can be introduced is \(35 \mathrm{~mole} \%\). Study of the recrystallization process leads to the identification
