钽酸铜的制备及其表征(含开题报告,外文翻译,毕业论文8200字,答辩PPT)
摘要
纳米粒子的调控合成是纳米科技发展的重要的组成部分，是探索纳米结构性能及应用的基础。本论文主要通过水热法和共沉淀法合成钽酸铜，并对合成的产物进行多种方法的表征。通过改变水热法的合成体系的实验条件如：保温温度，保温时间，添加不同的添加物等，进行一系列的对比试验；改变共沉淀法过程中的滴加物如：氢氧化钠，氨水等，进行对比实验。然后将各组实验所得的样品进行扫描电子显微镜检测和XRD物相定性分析检测，从而对比分析得出在实验室中制备钽酸铜的最佳方法和条件。

The preparation and characterization of copper tantalate
Abstract
Regulation of the synthesis of the nanoparticles is an important part of the development of nanotechnology, for exploring the basis of the performance and applications of nanostructures. In this thesis,copper tantalate was prepared by hydrothermal synthesis and coprecipitation synthesis, and products were characterized by a variety of methods . We conducted a series of comparative tests by changing the experimental conditions such as holding temperature , holding time, and different additives in the hydrothermal synthesis system. Then the samples were characterized by SEM and XRD, and finally through comparison and analysis we obtained the best methods and conditions of preparing tantalate copper tantalate nanocrystalline in the laboratory.
