摘要：
A method for manufacturing a composite ceramic body (24, 86, 96) with occluding a plurality of pores that are open at its surface of a porous ceramic body (28), the method includes the steps of impregnating a polysilazane solution (42) including polysilazane having a repetition structure of fundamental units of at least one of [-Si (H) (C n H 2n+1 ) -NH-] and [-Si (C n H 2n+1 ) 2 -NH-], and a predetermined organic solvent, into the plurality of pores of the porous ceramic body, and heating the porous ceramic body to convert the polysilazane in the plurality of pores into ceramic material.
