| ABSTRACT |
|
SrAl$_2$O$_4$ powder was prepared by polymerized complex method and its nucleation was observed at different temperatures and times. Problems of inhomogeneity and high synthesis temperature induced by solid state reaction could be solved by using polymeric precursors. The process of decomposition by heat treatment above 40$0^{circ}C$ was observed by Scanning Electron Microscopy (SEM) and elemental analyzer. Crystallization of SrAl$_2$O$_4$ occured at about 90$0^{circ}C$ and its crystalline size. which was determined by using Transmission Electron Microscopy (TEM) and X-Ray Diffractometer (XRD). was about 30∼50 nm. ﾖ⨀ ꂷ내 Ā ऀ 會Āऀ 䢷ﾖ⨀ 좸내 Ā ऀ 會Āऀ ꂷﾖ⨀ 내 Ā Ā Ā 會ĀĀ ﾖ⨀ Ⴛ내 Ԁ Ā 搀 會Ā搀 傸ﾖ⨀ 㢼내 Ā 저 會Ā저 ꢸﾖ⨀ 悽내 Ԁ Ā 搀 會Ā搀 ¹ﾖ⨀ 袾내 ഀ Ā 저 會Ā저 墹ﾖ⨀ 傟내 ऀ Ā 搀 會Ā搀 낹ﾖ⨀ 炠내 Ȁ Ȁ ᘀ ࢺﾖ⨀ 邡내 ̀ Ȁ ᘀ 悺ﾖ⨀ 셌 돀Ⴑﾖ⨀ |
