摘要：
A process for the treatment of polyorganosilazanes and/or polyorgano(disilyl)silazanes with an effective quantity of a catalyst system comprising (i) an ionic inorganic salt of the formula M.sup.30 A.sup.-, and (II) a compound capable of complexing with the cation M.sup.+ of the salt. The M.sup.+ cation is a metal ion or a quaternary ammonium ion, and A.sup.- is a compatible anion.The polysilazanes are selected from organopolysilazanes and organopoly(disilyl)silazanes. When treated in this manner, the polysilazanes are characterized by good thermal behavior and can, in particular, be used, after pyrolysis, as precursors of ceramic products.
