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.

[ What is claimed is:] [1.] A method of making a ceramic tube comprised of silicon and silicon carbide, said method comprising the steps of:covering a mandrel with at least one layer of a carbon fiber material;infiltrating the carbon fiber material covering with a thermoset resin;curing the resin-infiltrated covering to render the covering rigid and maintain the covering in a rigid state, forming a mandrel-supported green body;removing the mandrel from the green body to form a free-standing green body;treating the free-standing green body with graphite to fill voids in the carbon fiber material to render the graphite treated free-standing green body gas tight; andinfiltrating the graphite treated free-standing green body with molten silicon to form a hollow ceramic tube comprised of silicon and silicon carbide.
