【摘要】 报道了以流变相-先驱物法制备纳米氧化锡掺杂锑的软化学方法.首先用流变相反应合成草酸盐先驱物,然后用DTA和TG研究了先驱物在空气中的热分解过程;用X射线粉末衍射和IR光谱表征了热分解固体产物;透射电镜测得固体产物的颗粒尺寸在20nm以下.用紫外-可见分光光度计测试产物在44～2500nm范围内的吸波性能.流变相-先驱物法为制备纳米级吸波化合物提供了一种简单、可行、有效的方法.更多还原

【Abstract】 In this paper, we report a soft chemical route for the preparation of nano material SnO₂:Sb by therheological phase reaction- precursor method. First, the oxalate precursor was synthesized by rheological phasereaction. Then, thermal decomposition of oxalate in air atmosphere was studied by DTA and TG. The solid product ofthermal decomposition was characterized by X-ray power diffractometry and IR spectra. The particle size of 10-20nmhas been measured by TEM. The absorption of SnO Sb in 400～2500nm has been measured by UV3400spectrophotometer. The rheological phase reaction provides a simple, practicable and effective route for the synthesisof nano-absorption material.更多还原
