Objective: To study the application in classification of MCC by principal component analysis(PCA)and cluster analysis method. Method: Determined powder property and other physical properties of 12 kinds of PH101 and PH102 MCC types which obtained from 5 different manufacturers

then PCA and cluster analysis method were used to investigate the classification of MCC. Result: The same result was obtained from PCA and cluster analysis method

it revealed that the basis on classification of PH101 and PH102 MCC types by PCA. Conclusion: PCA and cluster analysis method can be applied to study the classification of MCC with the result was the same as classification of MCC in traditional production application.
