【Abstract】 This paper analyzed the cooling crystallization of special points in ternary phase diagram on the basis of law of phase and elementary knowledge of phase diagram.For the primitive compositional point located on the line connecting crystallization phase compositional points,its end product of cooling crystallization is the crystal phase represented by the two ends of the line on which the compositional point is.For compositional point located on the place of boundary line and non_variable points,its end product of cooling crystallization is the crystal phase represented by the three top points of a sub_triangular on which the primitive compositional points are.更多还原
