A novel, reformed polysilazane obtained by reacting a polysilazane with a compound selected from ammonia, primary and secondary amines, hydrazine and mono-, di- and tri-substituted hydrazines to cross-link the polysilazane with the compound serving as a cross-linking agent or to link the compound to the polysilazane.
