We demonstrate an effective method for formation of domain-inverted gratings in MgO:LiNbO3 for quasi-phase-matched nonlinear-optic devices. It was found that domain-inverted gratings could be obtained by application of voltage pulses with SiO2 insulation layer cladding. An insulation layer on the $-Z$ face reduces the leakage current, and another insulation layer over a periodic electrode on the $+Z$ face reduces excessive expansion of domain-inverted regions. Good-quality domain-inverted gratings with a period of 18 μm were obtained.
