수산화광물(水酸化鑛物)인 수골석(水滑石), Xonotlite, 활석(滑石), 투각섬석(透角閃石) 및 Antigorite의 열수합성(熱水合成) = Hydrothermal Syntheses of Hydrous Minerals, Brucite, Xonotlite, Talc, Tremolite, and Antigorite

다국어 초록 (Multilingual Abstract)

Dolomite and quartz, starting materials, were mixed by the mole ratio of dolomite versus quartz with 1 : 0, 1 : 1, and 2 : 1, and of which was heated under saturated water vapor pressure of $20kg/cm^2(211.4^{\circ}C)$, $80kg/cm^2(293.6/C)$ and $120kg/cm^2(323.1^{\circ}C)$, respectively, during 20 hours. The results of the hydrothermal syntheses are as follows: 1) calcite crystals were formed at all cases of the reation 2) brucite crystals were formed when dolomite was heated under the saturated vapor pressure of $80kg/cm^2$ during 20 hours. 3) talc, tremolite, xonotlite, and antigorite were formed under saturated vapor pressure of $80kg/cm^2$ by 20 hours reaction.
