PRECISION OF DISCLOSURE The present invention relates to a composition organopolysilazane which can crosslink by providing energy and with an effective amount of radical generators free. The energy contribution allowing to generate said radicals can be performed in the form of heat, ultraviolet radiation, of an electron beam. The crosslinked organopolysilazane compositions exhibit high thermal resistance and can be used in particular after pyrolysis, as precursors of ceramic products. |
