Patent number: 9193603Abstract: The present invention relates to an urchin-like iron oxide and a method for producing the urchin-like iron oxide. The urchin-like iron oxide comprises a core and multiple needle-like elongations protruded from the core. The needle-like elongations could be wire, rod, tube, cone, and flake. The length/width ratio of the needle-like elongation is high enough to apply in an optoelectronic field. The method in accordance with the present invention is to stably heat an iron-contained powder under room temperature by a thermal oxidation. The surface of the iron-contained powder is slow oxidized to form an urchin-like iron oxide with multiple uniform distributed needle-like elongations protruded from the surface. The size of each needle-like elongation is easily adjusted and changed by controlling the heating temperature. The method has advantages of simplified operation and lowered expense.Type: GrantFiled: December 12, 2012Date of Patent: November 24, 2015Assignee: NATIONAL CHUNG CHENG UNIVERSITYInventors: Yuan-Yao Li, Hsin-Chih Yu, Li-Chieh Hsu
