摘要
采用硬脂酸法,在900℃下焙烧4h,制备了层状钙钛矿氧化物K2La2Ti3O10,比传统的高温固相法焙烧的温度明显降低,焙烧的时间显著缩短。采用X-射线衍射仪对产物结构进行了表征。分析表明所得样品结晶良好,无明显杂峰出现,生成了单相的K2La2Ti3O10晶体。
Calcined at 900℃for 4h,a layered perovskite oxide K2La2Ti3O10 was prepared by stearic acid method, significantly reducing the calcining temperature and the calcining time compared with the traditional high temperature solid-state method.The crystal structure of the product was characterized by X—ray difiraction.The analysis showed that the samples crystallized well,with no impure peaks and a single—phase K2La2Ti3O10 crystal was generated.
