  The present invention relates to catalyst components and catalysts for olefinic polymerization. The catalyst components utilize magnesium chloride and silica as composite support, and the particle morphology thereof can be improved by regulating the ratio of magnesium chloride to silica. Further, the purpose of stabilizing the rate of catalytic polymerization reaction and improving the particle morphology of polymer so as to meet the requirements on catalyst performance of various polymerization processes can be achieved through the combination of the supports of the catalyst. In the meantime, when used in the polymerization of propylene, the catalysts of the present invention exhibit a relatively high polymerization activity and high stereospecificity.
