摘要: 本文用XRD、IR、DTA及ESR等方法研究了我国7种天然沸石矿样的结构、品位、酸性及其杂质组份与色泽的关系。这些矿样大都是丝光沸石与斜发沸石相伴而生。但其相对含量不一。此外,还有一种纯度很高的高岭土矿。它在常温下具有化学吸附空气中氧分子的能力。

Abstract: Seven natural zeolite minerals from different region of China have been studied byXRD, IR, DTA and ESR methods for the structure, purity and acidic property characteri-zation.It is found that six of the zeolite samples are twin minerals of mordenite and cli-noptilolite and have the following order according to their mordenite content: C-2≈NZ-3>NZ-7>NZ-2>NZ-1 Zeolite C-1 is a pures clinoptilolite.Mineral NZ-6 is a kaolinite of high purity.ESRmeasurements showed that all zeolite samples give Fe3+ in large content and different con-tent of Mn2+, while NZ-6 shows O2- signals in ESR spectra as a result of absorbed oxy-gen from air.
