溶胶一凝胶法的迅速发展促进了金属醇盐化学的研究 ,其结果又推动了溶胶—凝胶法研究的开展 .金属醇盐作为溶胶—凝胶法的前驱物( precursor) ,具有容易用蒸馏、重结晶技术提纯 ,可溶于普通有机溶剂 ,易水解等特性 .本文主要介绍了与溶胶—凝胶法有关的金属醇盐物化特性 The rapid development of sol-gel method has promoted the research of metal alkoxide chemistry, and the result has promoted the research of sol-gel method. Metal alkoxide, as the precursor of sol-gel method, Distillation, recrystallization purification technology, soluble in common organic solvents, easy hydrolysis and other characteristics.This paper mainly introduces the sol-gel method of metal alkoxide physical and chemical properties
