The Microstructure of Low Oxygen Nicalon Fibre
Fibers in the Nicalon series based on SiC but having a very low oxygen content (0.4% wt) have recently been produced by Nippon Carbon by curing the polycarbosilane precursors with an electron beam instead of thermal oxidation. The microstructure of the fibre has been studied by TEM and, as in the NL...

| Zusammenfassung: | Fibers in the Nicalon series based on SiC but having a very low oxygen content (0.4% wt) have recently been produced by Nippon Carbon by curing the polycarbosilane precursors with an electron beam instead of thermal oxidation. The microstructure of the fibre has been studied by TEM and, as in the NLM 202 fibre found to consist of C particle of 2–3 nm and SiC crystallites, but with larger dimensions (10–20 nm compared to 3 nm) due to the absence of a continuous Si-O-C intergranular phase. |
