| 内容記述 | Structures of (Ca_<2-x/2>□_<x/2>) (Si_<1-x>P_x)O_4 crystals were examined as a function of x ranging from 0.03 to 0.40. All of the samples were heated at the stable temperature region of the α-phase and then quenched in water. The phase constitution at ambient temperature was classified into three categories according to the fraction of the α-to-α´_H transition. When the transition was completed as in the crystals with x?0.100, the β- and α´_L-phases were obtained, the relative amounts of which were determined by the start and finish temperatures of the α´_L-to-β martensitic transformation. With 0.125?x?0.150, the α-to-α´_H transition was incomplete. During further cooling, the product α´_H-Phase was inverted to the α´_L-Phase, and the residual α-phase was inverted to the incommensurate phase successively. Because the start temperature of the α´_L-to-β transformation was lower than ambient temperature, the α´_L-Phase was stabilized. With x?0.175, all of the crystals were free from the α-to-α´_H transition. The crystals with 0.175?x?0.225 were made up exclusively of the incommensurate phase. A good correlation existed between the modulation wavelength (=N) and the P/ (Si+P) ratio (=x) as N=4.134-1.56x (0.175?x?0.250). With 0.275?x?0.300, the crystals were isostructural with α-Ca_2SiO_4. The hexagonal phase with 0.350?x?0.400, probably a transition product from the α-phase, showed two-dimensional modulations along the α-axis with N=2 and along the c-axis with N=3. | |||||||||||||
