水酸化鑛物인 水滑石, Xonotlite, 滑石, 透角閃石 및 Antigorite의 熱水合成

Hydrothermal Syntheses of Hydrous Minerals, Brucite, Xonotlite, Talc, Tremolite, and Antigorite

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/cm²(211.4℃), 80kg/cm²(293.6/C) and 120kg/cm²(323.1℃), 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/cm² during 20 hours. 3) talc, tremolite, xonotlite, and antigorite were formed under saturated vapor pressure of 80kg/cm² by 20 hours reaction.
