Abstract

Novel polysiloxazanes comprising --SiH.sub.2).sub.n NH-- and --SiH.sub.2).sub.m O-- as the main repeating units are provided. The polysiloxazanes are produced by reacting a dihalosilane or an adduct thereof with a Lewis base, with ammonia and water vapor or oxygen. From the polysiloxazane, novel silicon oxynitride shapes can be produced and the silicon oxynitride shapes are essentially composed of silicon, nitride (5 mols % or more) and oxygen (5 mol % or more).
