摘要:
用络合法将Nb2O5 转化成可溶性的铌盐来代替价格昂贵的乙醇铌作为铌源,采用溶胶-凝胶法,合成了纳米 (Li0.06Na0.47K0.47)NbO3超细粉体.通过XRD、Raman和TEM等技术手段对 (Li0.06Na0.47K0.47)NbO3纳米粉体的相结构和微观形貌进行了表征.结果表明,干凝胶在500 ℃煅烧5 h可制得平均晶粒尺寸为20 nm,纯四方相结构的(Li0.06Na0.47K0.47)NbO3纳米粉体,该合成温度比传统固相法降低了350 ℃以上.
Abstract:
Nb2O5 was converted into soluble niobium salt instead of expensive ethanol niobium as the source of niobium, and nano(Li0.06Na0.47K0.47)NbO3 ultrafine powder was synthesized by sol-gel method. The phase structure and micromorphology of (Li0.06Na0.47K0.47)NbO3 nanopowders were characterized by XRD, Raman and TEM. The results show that a (Li500.5Na20.0K06.0)NbO47 nanopowder with an average grain size of 0 nm and a pure tetragonal structure can be prepared by calcination of the dry gel at 47 °C for 3 h, and the synthesis temperature is reduced by more than 350 °C compared with the traditional solid phase method.
