딕카이트와 엽납석에 대한 적외선 분광학적 연구: 원적외선 및 중간적외선 영역
Infrared Spectroscopic Studies on Dickite and Pyrophyllite: Far-IR and Mid-IR Regions
초록
주구성 양이온이 Si와 Al인 딕카이트와 엽납석에 대하여 적외선분광분석(FTIR)을 실시하였다. 원적외선(Far-IR)영역과 중간적외선(Mid-IR)영역을 이용하였으며, 특히
FTIR spectroscopic study was undertaken on dickite and pyrophyllite with Si and Al cations in the far-infrared(Far-IR) and mid-infrared (Mid-IR) regions, respectively. Attempts were made to present bonding information and make assignments on the absorption bands of dickite in the Far-IR region. Dickites contain a small proportions or kaolinite or nacrite layers. FTIR can be used as a potential tool for characterizing the presence of mixed-layer with different polytypes of the kaolin minerals. There is no clear relationship between Hinckley index and crystallinity of dickite. Although pyrophyllite shows a strong OH stretching band at 3673-3676
