【摘要】 采用熔盐法研究了Ba(Sn0.1Ti0.9)O3铁电体粉体的制备工艺和粉体性质。探讨了在熔盐催化下,合成温度对Ba(Sn0.1Ti0.9)O3反应完全程度及粉体形态的影响。结果表明,当反应温度达到900℃时,在熔盐环境下即可合成单相固体Ba(Sn0.1Ti0.9)O3,随着反应温度提高,粉体尺寸变化不大,但当温度超过950℃时出现晶粒异常长大趋势。烧结陶瓷的形貌和介电性质显示陶瓷粉体烧结活性好且介电性质优良。更多还原

【Abstract】 The preparing process and properties of Ba(Sn0.1Ti0.9)O3 ferroelectric powders by molten-salt method were investigated. The effects of synthesis temperature on Ba(Sn0.1Ti0.9)O3 powders’ reaction completeness and morphologies under the catalyst of molten salt were discussed. The investigation results indicated that the single phase Ba(Sn0.1Ti0.9)O3 solid state solution could be synthesized at 900℃ under molten salt condition,the size of powders changed slightly with reaction temperature increased till to 900℃. The grain of powders appeared an anomaly enlarge trend while the treated temperature above 950℃. The morphology and dielectric properties of sintered ceramics showed ceramic powders with good sintering activity and dielectric properties.更多还原
