摘要

NbC containing ceramic composites were manufactured from poly(siloxane)/Nb/NbC filler mixtures by a high temperature reaction bonding process. During heating in an inert atmosphere the Si—O—C ceramic residue of the polymer reacted with the metallic Nb filler to form Nb x Si y , NbO and NbC. Samples with a high Nb/NbC ratio showed reduced porosity and increased hardness after pyrolysis at 1200°C.
