Effects of Compositional Variation on the Structure and Properties of Aluminoborosilicate Glasses
Abstract:
In alkaline earth aluminoborosilicate glasses CaO-B2O3-Al2O3-SiO2, the changes of structure and properties caused by variations in the ratio SiO2/B2O3 were investigated. The structure was investigated by Fourier transform infrared spectroscopy. The dielectric constant and tangent loss were measured at 1 MHz. Chemical durability was evaluated by weight losses of glass samples after immersion in HCl and NaOH solutions. The results indicated that the fraction of four-coordinated boron atoms (N4), chemical durability and dielectric properties increased with increasing SiO2/B2O3 replacements.
