Abstract
Crack-free, dense and either amorphous or crystalline, nonoxide monolithic ceramic shaped articles are produced at relatively low temperatures, by shaping a powder (P) of an infusible, organometallic ceramic precursor polymer (Pi) into a green body having a relative density of at least 65%, and thence pyrolyzing such shaped green body.
