中文摘要: 采用TiO2粉、CaO和Al粉为原料,经混匀、压制和烧结后,制备出中间合金Al3Ti相,利用XRD、SEM-EDS、XPS等手段,对反应后样品的物相组成、微观形貌和原子价态进行分析表征。结果表明,在烧结温度1 400 ℃、烧结时间30 min、铝钛比1.3和钙铝比1.6的条件下,烧结产物主要物相为Al3Ti、Al和CaAl2O4,烧结产物形貌呈现相间分布,TiO2存在逐级还原的现象,烧结法制备中间合金Al3Ti相是可行的。
Abstract:Al3Ti phase of intermediate alloy was prepared by mixing, pressing and sintering applying TiO2 powder, CaO and Al powder as raw materials. Phase composition, microstructure, and atomic valence state of samples were analyze and characterize by XRD, SEM-EDS, and XPS. The results show that Al3Ti, Al and CaAl2O4 are the main phases of the sintered products under the conditions including sintering temperature of 1 400 ℃, sintering time of 30 min, ratio of Al to Ti of 1.3, and ratio of Ca to Al of 1.6. The morphology of the sintered products shows phase distribution, and TiO2 is reduced step by step. It is feasible to prepare Al3Ti phase by sintering method.
