Abstract
A silicon carbide whisker production apparatus manufactured by placing a plurality of lidded reaction vessels in the longitudinal direction of an Acheson furnace at intervals, packing graphite grains in the gaps between the adjacent reaction vessels and around the reaction vessels along the longitudinal direction of the furnace starting with the furnace-side ends of terminal electrodes to form a surrounding heating zone, and packing a heat insulating packing around the surrounding heating zone.
