摘要
Two different subhydrated phases exist in the CaSO4-H2O system. There are CaSO4, 0.5 H2O (S.G I121, a = 1.267,7 nm, b = 0.692,8 nm, c = 1.203,3 nm, beta = 90.26) and CaSO4, 0.6 H2O (S.G. I222, a = 1.237 7 nm, b = 0.630 3 nm, c = 1.200 7 nm). Their respective stability domain in the P(H2o)-T diagram is determined.
