PRODUCTION OF BN-COMPOSITE MATERIALS

The invention comprises a process comprising infiltrating or infiltrating and coating a substrate with a boron-comprising precursor, and contacting the boron-comprising precursor with a nitrogen-comprising reactant to convert the boron-comprising precursor to BN or other a boron-nitrogen reaction pr...

Beschreibung
Zusammenfassung:	The invention comprises a process comprising infiltrating or infiltrating and coating a substrate with a boron-comprising precursor, and contacting the boron-comprising precursor with a nitrogen-comprising reactant to convert the boron-comprising precursor to BN or other a boron-nitrogen reaction product in the surface porosity or in the surface porosity and on the surface of the substrate. Composite materials comprising as one phase a substrate and BN or other a boron-nitrogen reaction product as a further phase, in surface porosity or in surface porosity and on a surface of the substrate, are claimed.
