The results indicate that the temperatures of the internal points lag behind the process temperature entirely; the temperature difference curve of internal point gradually rises with the increase of heating temperature and the time for keeping warm. By the slough off of the internal free crystal water and the corresponding crystal transformation of gypsum, one-dimensional size in the length direction of mold first continuously declines and then increases slightly, the shape of gypsum grain changes from acicular shape to bulky cylindrical or lamellar appearance, subsequently transformating to needle morphology shape., authors=FAN Zhenzhong,
