Glass-ceramics

Vitrification is a well-established waste treatment method that has been used for silicate based wastes to achieve waste volume reduction and improve chemical stability before further use. However, the poor mechanical strength of the vitrified products has led to a low commercia…

Impedance spectroscopy measurements were performed on a series of silica (SiO2 ) and silica-titania (SiO2 -TiO2 ) glasses over the frequency range 40 Hz-10 MHz and the temperature range 25-700°C in order to elucidate the origin of the dielectric properties of SiO 2 -TiO2 glass-c…
