| 摘 要： | 本文以钛酸四丁酯、冰醋酸、盐酸、六水合硝酸锌为主要原料,采用溶胶-凝胶法,以去离子水作为溶剂制备出具有钛铁矿结构的纯六方相ZnTiO3粉体,并利用TG/DTA,XRD,FE-SEM和FT-IR对其组织结构和形貌进行了研究。实验结果表明:前驱体干凝胶在550℃热处理4h可制得纯六方相ZnTiO3,且六方相稳定存在的温度范围相对较宽,从550℃到900℃。当温度升高到950℃后,六方相ZnTiO3将分解为立方相Zn2TiO4和金红石相TiO2。在550℃热处理制得的ZnTiO3粉体粒径约为50nm。

| Abstract: | Pure hexagonal ZnTiO3 powder was successfully synthesized by sol-gel method using deionized water as solvents.The as-prepared powders were characterized by thermogravimetric/differential thermal analysis(TG/DTA),X-ray diffraction(XRD),field emission scanning electron microscopy(FE-SEM) and Fourier-transforming infrared spectroscopy(FT-IR).The results showed that pure hexagonal ZnTiO3 powder could be obtained by calcining the resultant derived from sol-gel process at a relatively low temperature of 550.Moreover,it had been found that the pure hexagonal ZnTiO3 could exist in a relatively wide temperature range of 550～900℃.When the temperature increased up to 950℃,hexagonal ZnTiO3 would decompose into cubic Zn2TiO4 and rutile.The size of particles calcined at 550℃ is about 50nm. |
