【摘要】 以AlCl₃·6H₂O为原料,采用电化学方法制备了超细纳米Al₂O₃粉体,对粉体进行XRD及TEM表征,粉体不经热处理即含有γ-Al₂O₃。对粉体分别经500℃、800℃、950℃各处理2h,得到了粒径分别为20nm、35nm、60nm形态不同的粉体。更多还原

【Abstract】 AlCl₃·6H₂O as raw material is used synthesized nanosized alumina with electrochemical method. The powders with XRD and TEM are analyzed. There are γ-Al₂O₃ powders at room temperature, and calcined at 500℃, 800℃, 950℃ for two hours respectively, the ever size of powders are 20 nm, 35 nm and 60 nm each.更多还原
