摘要： 热致变色示温材料具有操作方便,测温范围广和不需要复杂仪器等优点,因而广泛用于宇航事业、热记录材料及传感器等。钒为我国丰产元素,钒化合物的热致变色研究报导不多[1]。本文报导氧钒(Ⅳ)化合物作为热致变色材料的探索。

关键词: 热致变色, 氧钒化合物

Abstract: The title compound was prepared by heating V2O5 and K2TiO(C2O4)2·2H2O in sulfuricacid solution.Its composition was ascertained by elemental analysis.The compound changesfrom green to yellow at 418℃.The mechanism of thermochromism is ascribed to thedehydration of the coordinated water as confirmed by ESR, TG, DTA and IR results.

Key words: thermochromism, vanadium oxide compound
