【摘要】采用微波法制备了纳米晶B aT iO3,并通过XRD、SEM、TG及原子吸收等对产物进行了表征.XRD分析表明晶体为立方相B aT iO3,SEM显示B aT iO3颗粒形貌主要为立方相,一次粒子的粒径约为50 nm,TG分析表明所制得的B aT iO3粉体晶形稳定,原子吸收分析表明所制得的B aT iO3粉体杂质总含量为0.0261%.更多还原

【Abstract】 The nano-crystalline Barium Titanate was prepared by the microwave method.The morphological feature of the product was characterized by ways of XRD,SEM,TG and atomic absorption.The result showed that the crystal was cubic phase structure by XRD analysis and the first grade grain size was about 50 nm by SEM;the crystal form was stable using TG;the amount of impurity was about the percent of 0.0261 by the atomic absorption.更多还原
