Transport properties of the sodium-yttrium-silicate glasses
Source abstract
Abstract
Abstract The influence of yttrium oxide on the transport properties and chemical stability of sodium silicate glasses is investigated. The seven sodium-yttrium silicate glass compositions were synthesised. There are three composition with Na 2 O/Y 2 O 3 = 6.5 and four with permanent Na 2 O content with 5 to 8 mol% of Y 2 O 3 . The thermal behaviour of the glasses was studied with dilatometric and DSC methods. The research into the electrical characteristics of the glass has shown that their electrical conductivity is in the range of 5 × 10 − 8 –10 − 6 S/cm at 25 °C and 10 − 3 S/cm at 300 °C. It is shown that the hydrolytic resistance increases when growing the Y 2 O 3 concentration in the glass composition at constant Na 2 O content.
