纳米晶钛酸钡的Sol-gel法制备及其尺寸效应
BaTiO3 尺寸效应 XRD 相变
2010/1/5
采用sol-gel法制备了不同粒径的钛酸钡（BT）纳米晶粉. XRD、Raman光谱和DSC测试结果显示,随着退火温度的升高，晶粒长大，晶胞的a轴逐渐减小， c轴逐渐增大.粒径在54 nm左右时，钛酸钡由顺电立方相向铁电四方相结构转变，在立方-四方相变过程中，晶胞略微膨胀.随着粒径的减小，正交-四方相变温度升高，四方-立方相变温度降低， Raman谱峰降低和宽化，粒径为38 nm左右时四方相的特征...
Sol-gel自蔓燃法控制合成二氧化钛纳米粉体及性能
Sol-gel自蔓燃 二氧化钛 纳米粉体 控制合成
2009/12/3
采用化学络合溶胶-凝胶法,结合自蔓燃合成工艺制备了结构可控、分散性良好的TiO2纳米粉体.考察了原料组成、凝胶膨胀程度和温度机制对粉体结构、分散性的影响,用漫反射光谱测试了所制备粉体的光吸收性能. 结果表明,将原料中氧化剂与还原剂的摩尔比从2增加到7,在600 ℃的煅烧温度下可以得到金红石含量在25％～68.2％之间的TiO2,这些结构不同的粉体粒度为30 nm左右;凝胶前驱体经过150 ℃充分膨...
用荧光光谱跟踪钙-海藻酸水溶液的Sol-gel转变
Sol-gel转变 物理凝胶化 荧光光谱 海藻酸
2009/11/13
为了克服传统方法在测定凝胶化点的同时, 作用力对物理交联点的破坏和对大分子链运动的干扰, 探索和建立不施加应力的凝胶化点测定方法, 采用荧光光谱跟踪了异硫氰酸荧光黄(FITC)标记海藻酸与钙离子在水溶液中螯合的物理凝胶化. 随着凝胶化的进行, 荧光相对强度和各向异性比在凝胶化时间曲线的80 min时出现了明显的转折点, 与Winter方法得到的凝胶化点(80 min)完全一致. 因此可以利用...
