CERAMIC MATERIALS FROM POLYCARBOSILANES ABSTRACT A method is disclosed for the preparation of ceramic materials with reduced oxygen levels from polycarbo- silanes by the pyrolysis of a mixture of a polycarbosilane, a hydrosilylation catalyst, and an unsaturated compound selected from the group consisting of reactive diolefins, reactive alkynes, polyolefins, vinylsilanes, and unsaturated siloxanes where the mixture is rendered infusible prior to pyrolysis by heating to relatively low temperatures in an inert atmosphere. This invention is especially well suited for the production of ceramic fibers from polycarbosilanes.
