Organosilicon Polymers as Precursors for Silicon-Containing Ceramics

摘要

Following general comments about the preceramic polymer approach to the preparation of ceramic materials, we describe the preparation of a novel polysilazane by dehydro-cyclodimerization of the ammonolysis product of Methylsilicon Hydrochloride , the conversion of such polymers to ceramic products and their use in upgrading polysilanes of type (CH3SiH)x(CH3Si)yn) and (CH3Si(H)CH2)n to more useful ceramic precursors.
