摘要： A method of producing a ceramic matrix composite is provided, which production method reduces metal residual percentage within matrix with little energy consumption, without requiring special external heating means and special equipment while it is industrially simple and at a low price. It is a method of producing a ceramic matrix composite having the steps of filling mixed powder obtained by mixing metal powder and boron nitride powder into a predetermined container to form a green compact having a porous structure, and infiltrating the above described green compact with molten Al to form a composite material containing metal boride and having aluminum nitride as a matrix. The green compact is formed by compressing the mixed powder whose mixing ratio of metal powder to boron nitride powder is 1:1.8 to 1:2.2 (molar ratio) so that porosity of the green compact is 34 to 42%.
