ABSTRACT:
Method for making elongated structures such as furnace tubes having at least one flat side from vapor deposited silicon or silicon carbide using a graphite mandrel having a plurality of elongated edge-mated elements held in place by end collars to which an electrical power source is connected. Rectangular tubes can be sawed apart to produce flat plates if desired.
