摘要
利用X射线衍射仪(XRD)、扫描电镜(SEM)、激光粒度分析仪(BT-2003)、比表面积-孔隙率分析仪(SA3100)以及动力学分析法等分析手段,研究了烧结温度对于氧化镁颗粒的相组成、微观形貌以及粒径、比表面积和活性等性能的影响。结果表明:经过煅烧后氧化镁晶体结构更完整;随着煅烧温度的升高,氧化镁颗粒明显变大且粒度大小逐渐趋于一致且比表面积逐渐减小,活性降低。
The X-ray diffraction, scanning electron microscopy, laser particle size analyzer, specific surface area-porosity analyzer and kinetic analysis methods are used to study the effects of calcination temperature on the phase composition, micro-morphology, particle size, specific surface area and activity of magnesium oxide particles. The results show that the crystal structure of magnesium oxide is more complete after the calcination.With the increase of the calcination temperature, the magnesium oxide particles become larger and the particle size gradually became uniform, the specific surface area decreases little by little, and the activity reduces.
