摘要

本文研究了以拟薄水铝石(AlOOH.nH2O) (n=0.62)和氢氧化镁(Mg(OH)2)为原料,在不同的反应时间下,微波水热合成镁铝尖晶石。利用x射线衍射(XRD)和傅里叶变换红外(FT-IR)研究了反应时间对镁铝尖晶石前驱体合成的影响。用扫描电镜研究了镁铝尖晶石前驱体的表面性能。XRD分析表明,氢氧化镁与拟薄水铝石反应生成氢氧化铝镁。在200 min时得到的样品中位直径为5.958 μm。当合成时间大于200 min时,结块现象非常严重。在150℃下烧结200 min后,烧结试样的组织更加致密,平均晶粒尺寸更小。烧结试样的平均晶粒尺寸为0.527 μm。微波等温合成和烧结镁铝尖晶石的最佳反应时间为200 min

Effect of Reaction Time on the Synthesis and Sintering of Magnesium-Aluminium Spinel by Microwave Hydrothermal Synthesis
In this study, microwave hydrothermal synthesis of magnesium-aluminium spinel from pseudo-boehmite (AlOOH.nH2O) (n=0.62) and magnesium hydroxide (Mg(OH)2) for different reaction times is researched. X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) are used to find out how the reaction time affects the synthesis of magnesium aluminium spinel precursors. The superficial properties of magnesium aluminium spinel precursors are investigated with scanning electron microscopy (SEM). According to XRD analysis, magnesium hydroxide reacts with pseudo-boehmite to form magnesium aluminium hydroxide hydrate. The median diameter of the samples obtained at 200 min was 5.958 μm. The agglomeration phenomenon was very serious especially when the synthesis time is greater than 200 min. The sintered sample obtained at 150°C for 200 min had more dense structure and smaller average grain size. The average grain size of the sintered sample was 0.527 μm. The best reaction time for microwave isothermal synthesis and sintering of magnesium aluminium spinel is 200 min. GRAPHICAL ABSTRACT
