Abstract
In some examples, a technique for forming a partially densified preform including ceramic particles may include mixing a densifying agent with metal oxide particles or metal oxide precursor to form a blended densifying agent, infiltrating the blended densifying agent in to a porous preform, pyrolyzing the infiltrated preform to convert the densifying agent to carbon and form a partially densified preform, and heat treating the partially densified preform to react at least some of the carbon with the metal oxide particles to form ceramic particles. Composite materials formed from porous preforms in which a blended densifying agent is disposed in pores of the preform are also described.
