Abstract
본 발명은 콜로이드 제올라이트의 불연속적인 입자의 콜로이드상 현탁액 및 투명한 테트라알킬암모늄 안정화 된 규산알루미늄 용액으로부터 이러한 제올라이트를 제조하는 방법에 관한 것이다. 이러한 규산알루미늄 용액에 잘 규정되고 조절된 금속 수산화물 용액 소량을 첨가하여 특정 제올라이트를 합성할 수 있을 뿐만 아니라 제올라이트 수율도 조정할 수 있다. 콜로이드상 현탁액은 기하 표준편차로서 표시되는 입자 크기 분포가 1.30미만, 바람직하게는 1.20미만이라는 사실과 함께 250nm미만, 바람직하게는 200nm미만의 평균 입자 크기를 갖는 것을 특징으로 한다. 본 발명에 따라 합성된 제올라이트 졸은 콜로이드상 현탁액에 전형적인 틴탈(Tyndal1) 광 산란을 나타내며 또한 작은 입자 크기 때문에 매우 낮은 침강 속도를 나타낸다. 본 발명에 따라 합성되는 제올라이트 졸은 무정형 물질을 거의 함유하지 않도록 제조될 수 있다.
