化学法SiO_2单组分凝胶纤维的制备

Preparation of silicon dioxide gel fiber with chemical process

用溶胶－凝胶低温合成方法制备了SiO2单组分凝胶纤维，纤维长大于1米。用旋转粘度计研究了溶胶－凝胶的转变过程，讨论了制备过程中各种条件对溶胶可纺性的影响，结果表明，较适宜的凝胶纤维制备TEOS：H2O：HCL：C2H5OH＝1：1．7：0．01：1（mol）

：Silicon dioxide gel fiberwhich length is over one metercan be prepared with cryochemical method．The paper research the col－gel transformation and influence of condition upon sol drawability during preparotion with stiring viscosimeter． In resultthe fit ratio of gel fiber preparation is TEOS：H2O：HCL：C2H5OH＝1：1．7：0．01：1（mole ratio）．
