| Abstract | Abstract- Alumina fibers were synthesized from two different systems, AiCI3-Ai powder-H20 and Ai(NO3)3-Ai powder-H20, by the sol-gel method. For the former system, gel fibers were obtained from solutions in a eomtxmifion range of Al powder/AICl ~ molar ratios of 2 to 5. For the latter system, the spinnable range was narrower compared to the aluminum chloride system. The thermogravimetry analysis (TGA) curve of the aluminum chloride system showed a weight loss up to 700 ~ while the TGA curve of the aluminum nitrate system showed no weight loss above 400 ~ which indicates that thermal decomposition f Cl- is more difficult than that of NO~-. |
