Glass samples of composition Na2O-B2O3:MnO were synthesized by the method of melt quenching (MQT). Dielectric permeability and dielectric loss for the samples were studied as a characteristic of temperature at different frequencies. The influence of the alloying oxide modifier on the studied parameters is interpreted. It was found that the dielectric constant of all studied samples depends on the composition, and the development of dipole relaxation in the studied glasses was also revealed. MnO-containing sodium glasses show an increasing presence of Mn2+ ions in glasses from C0 to C4, which function as modifiers. The dielectric constant of glass varies significantly with temperature, especially at lower frequencies.
