不同铝硅比对莫来石材料显微结构及性能的影响
Effect of Different Al-Si Ratios on Mullite Materials Microstructure and Its Properties
摘要
Abstract
Mullite main phase were prepared by solid state reaction using the bauxite and the gangue as the source of aluminum and silicon source respectively,aluminum fluoride and vanadium pentoxide as the additive.The mullite structure was characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM), and the corresponding EDS.Effects of different aluminum-silicon ratios on the porosity, water absorption, bulk density, flexural strength and microstructure of the samples were studied.The results show that when the molar ratio of bauxite and coal gangue was 3.05:2,the optimum values of the sample such as the apparent porosity of 23.6%,the water absorption of 10.55%,the bulk density of 2.3 g/cm3and the flexural strength of 114 MPa were obtained.关键词
