| Zusammenfassung: | A method of making a ceramic tube of silicon and silicon carbide comprising the steps of covering a mandrel with carbon fiber material; infiltrating the carbon fiber material with a thermoset resin; curing the resin to render the carbon fiber material rigid and produce a green body; removing the mandrel to produce a free-standing body; treating the free standing body with graphite to fill voids and render the green body gas tight and infiltrating the green body with molten silicon to form a silicon and silicon carbide ceramic tube. |
