Method of filling porosity of ceramic component

A method of fabricating a ceramic component, the method comprising:

• initially partially filling pores of a porous structure using one of a first processing technique or a second processing technique to form a preform body with residual porosity, the processing techniques differing with respect to the way that ceramic precursors are delivered into a green state and formation mechanisms of final ceramic materials from the ceramic precursors, the first processing technique including infiltration with a preceramic polymer material and thermal treatment to convert the preceramic polymer material to a ceramic material and the second processing technique including infiltration with a heated, liquid glass or glass/ceramic material and solidification of the liquid glass or glass/ceramic material to a solid glass or glass/ceramic material;
• when the first processing technique is used to initially partially fill the pores of the porous structure, thereafter performing the second processing technique to at least partially fill the residual porosity with the solid ceramic glass material;
• and
• when the second processing technique is used to initially partially fill the pores of the porous structure, thereafter performing the first processing technique to at least partially fill the residual porosity with the ceramic material.
