Process for the production carbothermal boride, cobalt and / or boride of nickel.

摘要

The inner chamber of an electric furnace, a tank of depot is loaded of a bed of the molten materials produced from boric acid as a fine grains of oxides has fine grains of the metal base and or of the metal base into small pieces, as well as of the carriers of carbon and which forms the - the top of the zone of the reduction of a layer forming a bed of the permeable to gases. The boron alloy is collected and taken off on the floor of the furnace. The process is applied to the production of a boron alloy based on cobalt and or of a boron alloy based on nickel. The bed of fusion with a carrier of carbon is constituted by the wood pieces 2 a 250mm is a quantity of 20 to 65, provided at the total quantity of carbon. The layer forming a bed of melting is maintained at a thickness of at least 500mm in which the wood is coked a dry wood charcoal.
