? 2022 Elsevier B.V.In this paper, we report on a new compound in the SrO-TiO2-B2O3 system. For the first time, the compound was synthesized by crystallization of glass tapes (GTs) obtained from a melt of 2SrO-2TiO2-B2O3. The crystallization was performed at 670 °C for 96 h. X-ray studies showed that the formed new phase belongs to the hexagonal system. The lattice parameters were calculated as well. It was suggested to attribute the new material to stoichiometric compound Sr3Ti3O6(BO3)2. The dielectric constant, tangent loss, ac and dc conductivities of the material were found to be almost constant in a wide range of temperatures. Investigation of varistor properties showed that the current-voltage nonlinearity coefficient is 2.05. The measurement of the hysteresis loop confirms the ferroelectricity of the material. It is found that the second-harmonic generation intensity of the new material exceeds that of KDP (by a factor of 3.2 for particles in the size range of 100 ÷ 150 μm).
