Abstract
A method is disclosed for the preparation of ceramic materials or articles by the pyrolysis of vinyl- or allyl-containing preceramic silazane polymers wherein the vinyl- or allyl-containing preceramic silazane polymers are rendered infusible prior to pyrolysis by high energy radiation such as gamma rays or an electron beam. Preceramic polymer compositions containing a vinyl- or allyl-containing silazane polymers and mercapto compounds containing at least two mercapto groups may also be rendered infusible by such high energy radiation. This method is especially suited for the preparation of ceramic fibers.
