초록

나트로라이트(Na-제올라이트)의 탈수현상에 따른 변화와 특성을 라만 및 X-선 회절실험을 통하여 고온, 동시적인 고온-고압 하에서 특성을 확인하였다. 고온실험은 최고 온도범위에 따라 ${\sim}450^{\circ}C$까지 증온한 XRD 실험에서는 가역적 변화를 관찰하였고, ${\sim}630^{\circ}C$까지 증온한 라만분광실험에서는 포스트라트로라이트로 상전이하는 비가역적인 변화를 관찰하였다. 감온과정 약 $380^{\circ}C$에서 포스트 나트로라이트 상이 나타나는 온도구간을 본 연구에서 새롭게 확인하였다. 동시적인 고온-고압 하(상온 < T < $300^{\circ}C$, 0 GPa < P < 2.1 GPa)에서 나트로라이트 분광선의 이동은 관찰되지 않았다.

In-situ Raman and X-ray diffraction experiments have been performed on mineral natrolite (Na-zeolite) to investigate the dehydration behavior under high temperature and high pressure-temperature conditions. XRD data show reversible dehydration up to $450^{\circ}C$ whereas Raman data show irreversible change when the material is heated up to $630^{\circ}C$. The existence of post-natrolite was newly identified to form from ${\beta}$-metanatrolite at $380^{\circ}C$ upon cooling. The formation of dehydrated metanatrolite under simultaneous high temperature-pressure (room temperature < T < $300^{\circ}C$, 0 GPa < P < 2.1 GPa) conditions was not observed.
