Abstract
 빠른 교반 조건에서 구조주형화합물인 TEAOH(Tetraethyl ammonium hydroxide)를 이용하여 제올라이트 SUZ-4를 성공적으로 합성하였다. 교반속도 250 rpm 이상에서 결정성의 제올라이트 SUZ-4를 얻을 수 있었다. 이것은 교반이 재현성있는 합성에 결정적인 역할을 한다는 것을 의미한다. 사용한 물의 양(H2O/Al2O3)의 차이에 의하여 SUZ-4 결정형태 조절이 가능하였다. XRD, BET 및 암모니아 TPD에 의해 SUZ-4의 물리화학적 성질 및 증기처리에 의한 열적 안정성이 조사되었다.

Zeolite SUZ-4 was successfully synthesized with TEAOH (Tetraethyl ammonium hydroxide) as structure directing agent under a vigorous stirring condition. Well-defined zeolite SUZ-4 structure was only obtained under stirring of 250 rpm or more. The results imply that stirring plays a pivotal role for reproducible synthesis. Morphology of SUZ-4 crystal was controlled by adjustment of water concentrations. The physicochemical characterization of SUZ-4 and its hydrothermal stability using a steam treatment were investigated by using XRD, BET, and NH3-TPD.
