초기 pH가 제올라이트성 ETS-계열의 결정화반응에 미치는 영향

The Effects of Initial pH on the Crystallization of Zeolitic ETS-Series

김화중, 김윤상

초록

새로운 미세공구조를 갖는 제올라이트성 물질인 ETS-4와 ETS-10의 합성에 pH가 미치는 영향을 조사한 결과, pH가 10.4인 경우 세공의 크기가 약 8Å인 ETS-10가 합성되는 반면 pH가 증가하면서 두 종류가 동시에 합성되는 것을 알 수 있었다. 그러나 pH가 11.5인 경우에는 순수한 ETS-4만이 합성되는 것을 알 수 있었다. Morphology를 보면 ETS-10의 경우 정점이 잘린 두 개의 피라미드를 겹쳐놓은 형상에서 pH가 증가함에 따라 순수한 ETS-4의 경우 판상형의 결정체들이 형성되는 것을 알 수 있었다.

The effects of initial pH on the synthesis of new microporus zeolitic materials, ETS-4 and ETS-10 were investigated with the initial pH from 10.4 to 11.5. The results showed that initial pH significantly affect the type of ETS-4 at pH. Micrographs show that the morphology of final solid product changes from the shape contacting the bottom sides of two truncated pyramids to the plane-like shape as initial pH increases.
