| 摘 要： | 采用硬脂酸法合成纳米晶SrMgxTi1-xO3(x=0.1～0.5)材料.用DTA,TG,XRD,IR,XPS和TEM进行表征.结果表明,粉末粒径d随SrMgxTi1-xO3中镁含量、烧结温度和烧结时间的改变而变化;烧结所产生的粉末粒度分布均匀、大小适中;Mg2+部分替代SrTiO3的Ti4+后,O的1s光谱随着Mg2+含量的不同而发生变化.

| Abstract: | SrMgx Ti1-xO3 nanocrystalline materials( x =0.1-0.5) were prepared by the stearic acid gel method. Powder samples were characterized by XRD, TG, DAT, IR, XPS and TEM. The results showed that the grain size d changed with the variations of Mg content x , the temperature of calcination and the time of calcination. The result of XPS showed that the binding energy of O 1s spectra changed with the change of Mg2+ content after the replacement of Mg2+ for Ti4+ . |
