“…Glass ceramics containing fluorine can be used, as bioactive materials, for the repair and reconstruction of diseased or damaged hard tissues (like bones and teeth) of humans [1]. Borosilicate glass ceramic containing alkaline compounds like CaO, known as ceramic packing materials, were used as high frequency (HF) and ultrahigh frequency (UHF) dielectric materials [2].…”

Two glass samples were prepared according to the molar formula (20%X–40%B2O3–40%SiO2), where X = CaO or CaF2. The glass was melted at 1300°C for 3 h until homogenous glass was obtained. The glass samples were heat-treated at 700°C for 2 h and at 850°C for different times. The green glass obtained has low dielectric constant and positive magnetic susceptibility. The molar volume, scanning electron microscope and differential thermal analysis studies showed that the crystallization rate increases with an increase in the sintering time. The replacement of CaO by CaF2 improves the physical properties of the glass. The existence of fluorine ions increases the electrical conductivity, magnetic susceptibility, molar volume, dielectric constant and effective overall reaction rate (κ). All measured properties have a random behaviour with sintering time due to phase separation and asymmetry of crystallization.
