| 摘 要： | 以B i2O3和S iO2为原料,一定浓度的双氧水为溶剂,采用水热法制备了硅酸铋(B i4S i3O12)粉体。用X射线衍射和扫描电子显微镜分析了合成粉体的相结构和形貌,用单因素实验法研究了反应时间、反应温度以及双氧水浓度对产物物相组成的影响,结果表明,在220℃下反应48 h,H2O2浓度4%~6%的条件下,可以合成微米级的纯相硅酸铋。

| Abstract: | Bismuth orthosilicate(Bi4Si3O12,BSO)powders were prepared by the hydrothermal synthesis method,using Bi2O3 and SiO2 as the raw materials and hydrogen peroxide solution as the solvent.The phase and the morphology of the as-synthesized powders were studied by X-ray powder diffraction and scanning electron microscope.The influence of the reaction time,reaction temperature,and the concentration of the hydrogen peroxide on the phase composition of the products were studied through single factor experiments.Exper... |
