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。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-1Zeolite C-1 is a pures clinoptilolite. Mineral NZ-6 is a kaolinite of high purity. ESRmeasurements showed that all zeolite samples give Fe^(3+) in large content and different con-tent of Mn^(2+), while NZ-6 shows O_2^- signals in ESR spectra as a result of absorbed oxy-gen from air.
