MÉTODO PARA PRODUZIR CARBONETO DE METAL DE TRANSIÇÃO E/OU CARBONETO COMPOSTO DE METAL DE TRANSIÇÃO

摘要

To simultaneously overcome a drawback in that proceeding of a solid phase carbonization reaction requires high temperature and a drawback in that the reaction requires use of expensive materials. A method for producing a carbide of a Group IVA, VA, or VIA transition metal in the periodic table and/or a composite carbide of the transition metal and iron, the method including the step of co-milling a ferroalloy containing a Group IVA, VA, or VIA transition metal in the periodic table and incidental impurities and a carbon material mainly composed of carbon in a vacuum or an atmosphere of an inert gas to effect a solid phase reaction between the ferroalloy and the carbon material.
