采用高温熔融法制备了中温固体氧化物燃料电池用系列硼硅酸盐玻璃,玻璃摩尔组成为40SrO-5La2O3-xAl2O3-(25-x)B2O3-30SiO2(x=0,2.5,5.0,10.0)。结果表明:随着Al2O3含量的逐渐增多,玻璃转变温度和析晶峰温度逐渐升高,而热膨胀系数(CTE)均在9.8×10-6/K左右,这与电极材料8%(摩尔分数)Y2O3稳定ZrO2(8YSZ)在相同温度范围内的CTE相接近。Al2O3摩尔含量为5%的硼硅酸盐玻璃在700℃热处理100h后未能检测到明显的析晶和CTE变化,同时与8YSZ电极材料在700℃保温100h没有观测到明显的界面反应,表明该玻璃具有良好的化学相容性。

采用固相反应合成法制备了(1-x)(0.96 Bi0.5Na0.5TiO3-0.04 BaTiO3)-xBi(Zn0.5Ti0.5)O3陶瓷(x≤0.10)。通过X射线衍射,介电温度谱等对该体系陶瓷的相结构及弛豫特性进行了研究。结果发现,该陶瓷在Bi(Zn0.5Ti0.5)O3加入量低于0.05时呈现纯钙钛矿结构。此外,随着Bi(Zn0.5Ti0.5)O3加入量的增加,其相结构由三方-四方共存向赝立方结构转变;同时,陶瓷的弥散因子上升,偶极子取向冻结活化能下降,表明BZT的加入明显地增加了0.96Bi0.5Na0.5TiO3-0.04 BaTiO3陶瓷的弛豫性。

一般的に紫外線遮蔽剤として用いられる金属酸化物は安全性に優れる一方,大量に配合すると感触や透明性などの使用性が悪くなるといった問題があった。この問題を解決するために,これまで感触に優れる球状粉体や板状粉体に紫外線遮蔽効果を有する金属酸化物を被覆する複合粉体などが開発されてきたが,金属酸化物を高濃度で被覆すると使用性が悪くなり,低濃度になると期待する紫外線遮蔽効果が得られなくなり,問題の解決には至らなかった。本研究では,これらの問題を解決するために,比較的広い範囲の紫外線を遮蔽する酸化セリウムに着目し,その形状を制御することを試みた。その結果,特定の条件で合成した球状,板状,および花びら状の酸化セリウムが,それぞれ特徴的な紫外線遮蔽…
