POLYMER HYDRIDE THIOSILAZANES, PRODUCTION THEREOF, SILICON NITRIDE-COWTAINING CERAMIC METERIAL CAPABLE OF BEING PRODUCED THEREFROM AND PRODUCTION THEREOF

摘要

The polymeric hydridothiosilazanes are prepared by reacting oligohydridoalkylsilazanes (RSiHNH)n with elemental sulphur in an ether as solvent. The polymeric hydridothiosilazanes can then be pyrolysed to give silicon-nitride-containing ceramic material.
