摘要
本文通过对阳原膨润土的物化性能测试和Ｘ射线物相分析，以大量的实验数据证明该地膨润土为钙镁基膨润土。因其含钙镁离子较多，层电荷高，具有较好的吸附性和阳离子交换性能，有广泛的工业用途和开发前景。
On the basis of a large number data obtained from the authors personal analyses chemically,physically, including that ofx-ray phases,the paper givers a detailed description on thenature of the bentonite from yangyuan County, Hebei Province. According to the authors, thebentonite is a kind of Ca-Mg base one of good quality. With vast ammount of Ca++,Mg++ ions andhigh layer electricity, it bears strong functions in adsorption and ion exchange and, therefore itsuse in industry is quite broad, of course, the prospect of its develop ment lies in painstaking processing.
