Abstract

Powder samples of natural lawsonite (Ca-lawsonite, $CaAl_2Si_2O_7(OH)_2{\cdot}H_2O$) was studied structurally up to 8 GPa at room temperature using monochromatic synchrotron X-ray powder diffraction and a diamond anvil cell (DAC) with a methanol : ethanol : water (16 : 3 : 1 by volume) mixture solution as a penetrating pressure transmitting medium (PTM). Upon pressure increase, lawsonite does not show any apparent pressure induced expansion (PIE) or phase transition. Pressure-volume data were fitted to a second-order Birch-Murnaghan equation of state using a fixed pressure derivative of 4 leading to a bulk modulus ($B_0$) of 146(6) GPa. This compression is further characterized to be isotropic with calculated linear compressibilities of ${\beta}^a=0.0022GPa^{-1}$, ${\beta}^b=0.0024GPa^{-1}$, and ${\beta}^c=0.0020GPa^{-1}$.

자연산 로소나이트(Ca-Lawsonite, $CaAl_2Si_2O_7(OH)_2{\cdot}H_2O$) 분말의 압력증가에 따른 변화와 구조적 특성을 소형 압력 발생장치인 다이아몬드 앤빌셀과 실시간 싱크로트론 X-선 회절실험을 통하여 확인하였다. 본 연구에서 시료에 적용한 압력은 1 기압에서 8 GPa 까지였으며 메탄올, 에탄올, 물의 혼합 용액을 압력 매개체로 하여 상온조건에서 실험하였고, 특이한 상전이나 압력하 부피변화의 이상현상은 발견되지 않은 가역적 압축특성을 관찰하였다. 최고압력까지 로소나이트는 결정성을 잃지 않는 것으로 확인되었고 압력증가에 따른 체적감소를 통해 체적탄성률($B_0$)을 계산해 본 결과 146(6) GPa로 도출되었다. 체적탄성률과 함께 계산된 선형압축률은 a-, b-, c-축에서 각각 0.0022, 0.0024, $0.0020GPa^{-1}$로 압력에 의한 부피감소는 대체적으로 3축이 같은 비율로 감소하는 것을 확인하였다.
