“…The reason for this behavior is that, the electric dipoles move almost parallel to the ac external electric field and create an inverse internal electric field. With the increase of temperature the movement of the electric dipole is easier and the dipoles move parallel to the ac external electric field and then the internal electric field increased and acts to decrease the dielectric constant [19,23]. It is also found that all samples exhibited similar behavior.…”

“…Many glasses exhibit a roughly linear behavior with changing their chemical composition. But glasses containing two different alkali oxides represent a major exception to this trend due to the mixed alkali effect (MAE) or mixed alkali earth effect (MAEE) phenomenon [20]. For the studied glasses, the deviation from linearity may be so great that two maxima (at 40 mol% and 55 mol%) and minima (at 35 mol% and 45 mol%) occur.…”

“…For the studied glasses, the deviation from linearity may be so great that two maxima (at 40 mol% and 55 mol%) and minima (at 35 mol% and 45 mol%) occur. Moreover, the MAE was observed as a dramatic nonlinear trend due to the introduction of alkali (K + ) and alkaline earth (Ca 2+ ) cations, where the resistance increased with increasing the difference between the radii of both the alkali and alkaline earth cations [20,21]. The concentrations of both CaO and K 2 O in all samples were calculated and exhibited in Table 2.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
