• [Display omitted] •Alkoxide-Hydroxide sol-gel method is used for the synthesis of barium titanate-surfactant Nanocomposite in inert atmosphere.•Effect of SDS on the dispersion of BT powder was studied at different sintering temperatures under microwave heating.•It is found that 0.5% surfactant-based BaTiO3 nano powder revealed the best results without losing dispersity.•At 1100 °C, the sintering temperature, 0.5% surfactant-based BT exhibited a density of 97.7% and dielectric constant of 9488.•The leading parameters of breakdown strength as 3.12 kV/mm, FOM as 9.98×103, and piezoelectric constant (d33) as 153 pC/N. Barium titanate (BaTiO3) nanopowder was synthesized by the alkoxide-hydroxide sol–gel process in an inert (N2) atmosphere. The effect of surfactant sodium dodecyl sulfate (SDS) concentration on the dispersion of BaTiO3 powder was studied at different sintering temperatures, under microwave heating. The phase and structural analysis revealed that the addition of surfactant did not affect the phase transformation of barium titanate. The best outcome was obtained in the case of 0.5 % surfactant-based BaTiO3. At 1100 °C sintering temperature, 0.5 % surfactant-based BaTiO3 exhibited a maximum density of 97.7 %, dielectric constant of 9488, the leading parameters of breakdown strength as 3.12 kV/cm, the figure of merit as 9.98 × 103, and the piezoelectric constant (d33) as 153 pC/N. Moreover, the energy density of 86 kJ/m3 with an energy efficiency of 27.43 % was attained at 1100 °C. For pure BaTiO3 nanopowder, the energy density and the energy efficiency were found as 66.85 kJ/m3 and 50.42 % at 1250 °C, respectively.
