Sr-doped Y2Ti2O7 has been synthesized by hot-pressing sintering in the vacuum with graphite die. The thermogravimetric analysis, electrical conductivity, dielectric and microwave absorption properties of Y2-xSrxTi2O7-δ (x = 0.05, 0.1, 0.15, 0.2) investigated. The ε′ of Y1.8Sr0.2Ti2O7-δ is four times larger than the pure Y2Ti2O7 and twice larger than that of Y1.8Ca0.2Ti2O7-δ at 8.2 GHz. The ε’’ of Y2-xSrxTi2O7-δ is also enhanced significantly. The reflection loss of Y0.85Sr0.15Ti2O7-δ with a thickness of 0.85 mm reaches a maximum absorbing peak of − 29.68 dB and bandwidth (reflection loss ≤ − 5 dB) of 2.9 GHz. These findings pave the way for the development of high dielectric constant materials operating in the 8.2–12.4 GHz region with potential applications in thin and efficient microwave absorber.
