Abstract:

SrTiO3 was synthesized by microwave heating. The shorter synthesis time and simpler processing show the potential applications of the mirowave synthesis method. The influence of synthesis conditions on the product properties was discussed in detail. The results show that the microstrcture and grain size distribution of SrTiO3 obtained by employing microwave heat are better than that produced by conventional heating.
