PRODUCTION OF OXYGEN-FREE OR LOW-OXYGENCONTENT SILICON CARBIDE MOLDING

The prodn. of oxygen-free or low-oxygen moulded silicon carbide prods., esp. fibres, comprises spinning polymeric organo-Si cpds. with reactive centres, e.g. polysilanes and polycarbosilanes, under inert conditions, followed by dimensional stabilisation in presence of reactive gas or by thermal trea...

Zusammenfassung:	The prodn. of oxygen-free or low-oxygen moulded silicon carbide prods., esp. fibres, comprises spinning polymeric organo-Si cpds. with reactive centres, e.g. polysilanes and polycarbosilanes, under inert conditions, followed by dimensional stabilisation in presence of reactive gas or by thermal treatment, and then by pyrolysis at above 1000 degrees C under anaerobic conditions in inert atmos..
