Neue Schichteinlargerungsverbindungen des schalenfoermigen Halloysits als Wirtsgitter (I) (Chemische Charakterisierung des japanisohen Nagano-Halloysits durch Intercalationsreaktionen)

Bowl-형 Halloysite를 Host 격자로 한 새로운 Intercalation 화합물(I) (화학반응성에 따른 Nagano-Halloysite의 특성화 연구)

Abstract

Bowl 형태의 일본산 Nagano 점토에 대한 분류 및 특성화 연구를 하였다. 결정입자 크기를 1$\mu$ 이하로 침강분리 시킨후 전자현미경으로 결정형태를 관찰하였다. 아울러 결정형태, 구조적 결함 및 intercalation 반응성의 상호관계를 검토하기 위하여 tube 형태의 한국산 halloysite 및 plate 형태의 kaolinite를 비교 조사하였다. 특이한 Bowl 형 Nagano 점토는 tube형 halloysite와 화학 반응성에서 동일하여 극성 내지는 hydrogen bridge 결합을 하는 guest 분자와 반응하여 층간삽입 화합물을 형성 하였다. 화학반응성에 따른 점토분류방법에 의해 Nagano 점토가 halloysite임을 밝혔으며 아울러 결정의 형태는 반응성에 영향을 미치지 않음을 알 수 있었다.
