M ssbauer 효과에 의한 제주도 찰흙의 함철 광물의 열적 거동과 상변환에 관한 연구
A Study on the Thermal Behavior and Phase Transformation of Iron-bearing Minerals in Clay of Cheju Island by M ssbauer Effect
초록
Based on the X-ray powder diffraction (XRD) and M ssbauer spectroscopy, the thermal behavior and phase transformations of two clays are investigated for raw and fired conditions, which are collected from Kwangryeongli and Ildo district in Cheju Island. M ssbauer spectra at room temperature and 20for two clays show that paramagnetic Fe3- is the structural iron of the layer silicate and ferrihydrite, and superparamagnetic goethite has about 50% of total iron contents. The XRD peaks of hematite for the fired clays appear from 80
