Preparation and Microstructurai Evolution of Sol-Gel-derived Enstatite Fibers
Homogeneous and transparent enstatite fibers were prepared via the sol-gel process of metal alkoxide precursors.The gel-to-ceramic conversion was characterized.The solution compositions had a significant influence on the microstructural evolution of gel fibers.Infrared studies indicated that bidentate bridging ligands were formed between acetate and metal ions,which enhanced spinnability remarkably.The as-drawn fibers were essentially microporous.On heating to 800 ℃,enstatite ceramic fibers exhibited mesoporous structures with nanocrystals in size.The optical transmittance of enstatite ceramic fiber in the visible range was around 90 % after heating at 800 ℃.
