Abstract
A method to form a displacement includes disposing a powder blend (comprising a plurality of ground ceramic particles and a plurality of ground resin particles) into a mold, densifying the powder blend while in the mold, heating the mold to form a first displacement, impregnating said first displacement with a polymer precursor compound to form a second displacement, and heating the second displacement to form a third displacement.
