The incorporation of titanium oxide in glasses is widely practiced. From the more fundamental aspect the contribution of the titanium ion to the dielectric properties, particularly the dielectric constant, is of special interest. The dielectric constant of glasses in the TiO2-Na2O-SiO2 system has been measured up to 1010 cycles per second. These glasses have dielectric constants as high as 13 even...
It is known that the electrical conductivity of most inorganic glasses is electrolytic in nature and generally determined by its alkali metal content. It has been shown1 from simple assumptions of elasticity and of ionic crystal theory that the Na+ ion has the highest conductivity in glasses, and all observations indicate this. The high mobility of the alkali metal ion is also shown in the high dielectric...
