MgTiO3 nanoplatelets were successfully synthesized by combining the sol–gel method with the molten salt method at low temperatures. The results show that the calcined process of the mixture sample (Mg–Ti gel and the eutectic salt NaCl–KCl at a molar ratio of 1:10) consists of a series of oxidation and combustion reactions in air. High purity MgTiO3 without other crystal phase can be obtained over 600°C for 2h. MgTiO3 synthesized at 700 and 800°C is regular in shape with crystal size of about 200nm in diameter and 50nm in thickness. The present work offers us a new route to synthesize well-dispersed MgTiO3 nanoplatelets with regular crystal morphology. A novel route to synthesize MgTiO3 nanoplatelets is reported. The above SEM images show that MgTiO3 nanoplatelets are regular in shape with crystal size of about 200nm in diameter and 50nm in thickness. All MgTiO3 nanoplatelets are well-dispersed.
