电子陶瓷用钛酸钡纳米粉中钡钛的分析方法对比

Comparative analysis and study on the Ba and Ti constituents of BaTiO3 electronic ceramic nanopowders

本文对两种分析方法进行了实验比较,分别测定了电子陶瓷用钛酸钡纳米粉体中钡钛的含量.硫酸钡重量法与铝还原法测定钡钛的标准偏差为0.047%和0.055%;且测定钛的准确度较高.络合滴定法测定钡钛的标准偏差为0.039%和0.049%;且测定钡的准确度较高,同时具有快速简便的特点.

Barium and Titanium in barium titanate electronic ceramic nanopowders are determined by two main chemical analysis methodsusing barium sulphate volumetric precipitation method and aluminum as reducing agent. RSD is 0.047% and 0.055%, high in determining accuracy for titanium were determined. Another one is determined with complexometric titrimetry. RSD is 0.039% and 0.049%, and high in determining accuracy for barium is determined.
