【摘要】：采用鈦酸四正丁酯和無水氯化鈣用溶劑熱法制備鈣鈦氧化物多孔納米結(jié)構(gòu),考察水熱溫度對鈣鈦氧化物多孔結(jié)構(gòu)粉體的影響,通過壓片燒成,考察不同燒成溫度對鈣鈦氧化物多孔納米結(jié)構(gòu)熱穩(wěn)定性的影響。利用X射線衍射(XRD),掃描電子顯微鏡(SEM),透射電鏡(TEM)和差熱-熱重分析(TG-DTA)等測試對樣品的晶相、顯微結(jié)構(gòu)和熱變化進行分析,通過測試燒成后樣品的吸水率和顯氣孔率等探究對其多孔性能的影響。結(jié)果表明:水熱溫度180℃制備的CaTi_2O_4(OH)_2樣品呈現(xiàn)疏松多孔結(jié)構(gòu)。壓制成型后在600~1100℃煅燒下,CaTi_2O_4(OH)_2樣品材料呈現(xiàn)多孔性,其顯氣孔率為44.28%。
[Abstract]:Porous nanostructures of perovskite oxide were prepared by solvothermal method using tetrabutyl titanate and anhydrous calcium chloride. The effect of hydrothermal temperature on porous structure powder of calcium titanium oxide was investigated. The effects of different sintering temperatures on the thermal stability of porous caloric titanium oxide nanostructures were investigated. The crystalline phases of the samples were measured by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and differential thermogravimetric analysis (TG-DTA). Analysis of microstructure and thermal change, The effects of water absorption and apparent porosity on porous properties of CaTi_2O_4(OH)_2 samples after sintering were investigated. The results showed that the CaTi_2O_4(OH)_2 samples prepared at 180 鈩，
