Abstract
Metal carbides are obtained by heating the metal of which the carbide is to be formed in a finely divided condition in admixture with a carbonizing mixture containing manganese dioxide in a hermetically sealed box. Preferably, the carburizing mixture consists of charcoal, manganese dioxide, caustic potash and ammonium chloride. A temperature of 1200 DEG C. may be employed, the product being cooled slowly out of contact with air. The metals so treated include tungsten, ferro-tungsten, titanium, ferro-titanium, molybdenum. and ferro-molybdenum. Reference is made to the production of alloys consisting of carbides of iron and tungsten, or carbides of iron, tungsten and chromium, or carbides of iron and chromium.ALSO:Mixtures of metal carbides are obtained by heating the metals of which the carbides are to be formed in a finely divided condition in admixture with a carburizing mixture containing manganese dioxide in a hermetically sealed box.
