국내산 천연 제올라이트의 열적 안정성에 관한 연구 = A Study on the Thermal Stability for Domestic Natural Zeolite, Heulandite

다국어 초록 (Multilingual Abstract)

Natural zeolites have recently been focused on due to their versatilities in possible industrial applications. Among several different types of domestic natural zeolites, clinoptilolite, in particular is one of highly prospective domestic natural zeolite. However, the isostructure of clinoptilolite, heulandite is always possible to coexist with clinoptilolite. Unfortunately, heulandite is thermally very unstable restricting its application to industrial process.
In this research program, domestic natural zeolite, heulandite was chosen to study the effects of ion exchanges and heat-treatments on the thermal stability. Two different ion-exchanging experiments were carried out followed by heat-treatments at different temperatures.
X-ray and IR spectroscopic analyses showed the enhancements in thermal stabilities of heulandite by Na+ cation exchanges.
