Abstract

PURPOSE: To massproduce α-Si3N4 with a high purity by nitriding of Si powder with a hitriding gas blown into the furnace from the peripheral surface of the upper portion of the enclosure supplying thereof through a iron cloth from the top of a vertical furnace via material distribution pipe, followed by intermittent withdrawal of resultant nitride from the bottom.
