摘要：以硝酸铝和甘氨酸为原料,采用自燃烧法,在不改变制备工艺的前提下,通过调整原料的配比,成功实现了α-Al2O3由纳米粒子到纳米片的可控合成,获得了分散性良好、尺寸均一的α-Al2O3纳米片.并通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射(XRD)、傅里叶变换红外(FTIR)光谱、热重-差示热分析法(TG-DTA)等手段对产物形貌、结构及前驱物的热性质等进行了研究.系统探讨了α-Al2O3纳米材料不同形貌和尺寸对其抛光性能的影响,结果表明,尺寸小且为片状纳米结构的α-Al2O3具有最佳抛光性能.这些实验结果对于α-Al2O3纳米材料的工业生产及其在抛光领域的实际应用具有借鉴意义.
α-Al2O3 nanoflakes with good dispersion and uniform size were controllably synthesized using a selfburning method under similar conditions and with aluminum nitrate and glycin as raw materials. Product structure was studied by transmission electron microscopy （TEM）, scanning electron microscopy （SEM）, X-ray diffraction （XRD） and Fourier transform infrared （FTIR） spectroscopy, etc. Thermodynamic properties of the precursor were studied using thermogravimetry-differential thermal analysis （TG-DTA）. The effects of different morphologies and sizes of α-Al2O3 nanomaterials on their polishing property were investigated for the first time. Results of the polishing study indicate that the small size nanoflakes with a high purity quotient have the best polishing property compared to other α-Al2O3 materials. This study is expected to have potential value for the industrial production and practical application of these α-Al2O3 nanomaterials in the polishing field.
