Al_2O_3 Na_2O CaO SrO系统富Al_2O_3区域固态反应的研究

Study on Solid state Reaction of Al 2O 3 Rich Region in Al 2O 3 Na 2O CaO SrO System

用理学Ｘ射线衍射仪、ＴＧ－ＤＴＡ、ＩＲ－４４０ 红外光谱研究了Ａｌ２Ｏ３－Ｎａ２ Ｏ－ＣａＯ－ＳｒＯ系统富Ａｌ２Ｏ３ 区域固态反应。实验结果表明，煅烧过程固态反应的最终物相组成为Ｎａ２Ｏ·１１Ａｌ２Ｏ３，ＣａＯ·６Ａｌ２Ｏ３ ，ＳｒＯ·６Ａｌ２Ｏ３ 与α－Ａｌ２Ｏ３

In this paper,the solid state reaction of Al 2O 3 rich region in Al 2O 3 Na 2O CaO SrO system is studied by X ray diffractometer,TG DTA and IR 440 infrared spectrometer The experimental results show that the final phase composition of solid state reaction in the calcinating process are Na 2O·11Al 2O 3,CaO·6Al 2O 3,SrO·6Al 2O 3 and α Al 2O 3
