在 CaO-A120 3-SiO z-H20 (CASH) 系统中，合成了硅灰石、硅灰石 II tc、硅灰石 II m、玫瑰石、叶腊石 1 tc、黝帘石、斜长石、硬铝榴石、葡萄石、钙铝榴石、玛格丽特、钙长石和刚玉等相。纯化学品并通过 X 射线衍射法进行广泛表征。首次制备了高压单斜晶系CaSiO 3 硅灰石II m。这些纯合成相以及天然石英和实际上端元组成的蓝晶石，已用于实验研究以下单变量反应：(1) 1 硅灰石= 1 硅灰石 II tc (2) 1 硅灰石= 1 硅灰石 IIm (3) 1 硅灰石 II m= 1 硅灰石 II tc (4) 1 玫瑰石= 3 硅灰石+ 1 H20 (5) 1 玫瑰铁矿= 3 硅灰石 IIm+ 1 HzO (6) 1 叶蜡石= 1 刚玉+ 4 石英+ 1 H20 (7) 6 黝帘石= 6 钙长石+ 2 钙铝榴石+ 1 刚玉+ 3 H20 (8) 4 黝帘石+ 1 石英= 5 钙长石+ 1 钙长石+ 2 H20 (9) 2 黝帘石+ 1 蓝晶石+ 1 石英= 4 钙长石+ 1 H20 (10) 4 橄榄石= 2 黝帘石+ 1 蓝晶石+ 1 石英
In the system CaO-A120 3-SiO z-H20 (CASH), the phases wollastonite, wollastonite II tc, wollastonite II m, rosenhahnite, pyrophyllite 1 tc, zoisite, clinozoisite, lawsonite, prehnite, grossular, margarite, anorthite, and corundum have been synthesized from. pure chemicals and extensively characterized by X-ray diffractometry. The high pressure monoclinic polymorph of CaSiO 3, dubbed as wollastonite II m, has been prepared for the first time. These pure, synthetic phases along with natural quartz and a kyanite of practically end member composition, have been used to experimentally investigate the following univariant reactions:(1) 1 wollastonite= 1 wollastonite II tc (2) 1 wollastonite= 1 wollastonite IIm (3) 1 wollastonite II m= 1 wollastonite II tc (4) 1 rosenhahnite= 3 wollastonite+ 1 H20 (5) 1 rosenhahnite= 3 wollastonite IIm+ 1 HzO (6) 1 pyrophyllite= 1 corundum+ 4 quartz+ 1 H20 (7) 6 zoisite= 6 anorthite+ 2 grossular+ 1 corundum+ 3 H20 (8) 4 zoisite+ 1 quartz= 5 anorthite+ 1 grossular+ 2 H20 (9) 2 zoisite+ 1 kyanite+ 1 quartz= 4 anorthite+ 1 H20 (10) 4 lawsonite= 2 zoisite+ 1 kyanite+ 1 quartz
