陶粒是一种新型建筑材料。我们用红外光谱分析等方法得出了下列结果:陶粒膨胀的内动力主要是原料中的结构水(-OH)的气化,其次是由Fe_2O_3氧化还原反应所产生的CO_2气体。
Ceramsite is a new type of building material. We obtained the following results by IR spectroscopy and other methods: The internal motivation of ceramsite expansion is mainly the gasification of structural water (-OH) in the feedstock, followed by the CO 2 gas produced by the redox reaction of Fe 2 O 3.
