Analysis of Electric Conductive Activation Energy from the Electric Conductivity of Silicate and Borate Glasses

摘要：

　　This work is to compare the electric conductive activation energies with increasing Na2O in SiO2 and B2O3 glasses.The electrical conductivity is measured by TER2000 analyzer and it is compared with value calculated by Arrhenius equation.The conductivity of SiO2 system glasses is higher than B2O3 system glasses,and the highest value is 1.36 × 10-4 Ωcm-1 in 60SiO2-40Na2O glass.The activation energy from conductivity is proportion to temperature and inverse proportion to Na2O contents.The activation energy is analyzed from density and CTE (thermal expansion coefficient).
