The Structure of Layered Silicate Mineral and Their Vibrational Spectra Characteristics
摘要
Abstract
Using near-infrared analyzer to test layered silicate minerals, accessing to six kinds of near-infrared spectra of layered silicate minerals, according to the principle of the structural mineralogy and the principle of near-infrared spectrum, analyzing representative layered silicate minerals with 2:1 type structure unit such as talc, pyrophyllite, muscovite, illite and representative layered silicate minerals with 1:1 type structure unit such as kaolinite and serpentine, 1:1 type structure of layered silicate as between two cell layers has a longer hydrogen bond, the longer hydrogen bond widen the stretching vibration spectrum band of O-H and also move it to the direction of the long wave band, sometimes could appear bimodal phenomenon. In addition, comparing layered silicate minerals having dioctahedral structure with layered silicate minerals having trioctahedral structure, the absorption intensity which is caused by the stretching vibration frequency of O-H is stronger in layered silicate minerals having dioctahedral structure. As for layered silicate minerals with dioctahedral structure, the stretching vibration frequency of O-H is mainly affected by the cations combining with hydroxyl in octahedra.关键词
