Abstract
A process for the preparation of metal carbides or mixtures thereof comprises reacting under an atmosphere of inert gas or gaseous hydrocarbon or mixtures thereof and at a temperature of at least 1500 DEG F. at least one metal component selected from Groups IIIB, IVB and VB of the Periodic Table (as published by the Fischer Scientific Company) including the rare earth and the actinide elements 90 to 94, and alloys, halides, sulphides and oxides thereof, with a carbon source selected from carbon, hydrocarbons and alkaline earth metal carbides, by contacting said reactants in a molten menstruum comprising metallic sodium or potassium or a mixture thereof, and, when using said metal oxide, a reducing metal selected from calcium, magnesium, lithium, strontium and barium in at least the stoichiometric amount required to reduce the metal oxide, and separating the metal carbide from said molten metal menstruum. The separation may be achieved by distilling off the sodium or potassium, or by filtration or digestion of the same in methanol. A flux may be added to aid the solution of the reactants, e.g. NaCl, KCl, NaF or CaCl2, and may be formed in situ if a halide reactant is used. When a metallic reducing agent is present as described above this may also be formed in situ by adding an easily reducible compound of the metal, e.g. CaCl2. When the carbon source is carbon itself the presence of an alkaline earth metal, e.g. Ca or Mg, increases the solubility of the carbon and thus promotes the reaction. Impurities in the product such as NaCl or KCl may be removed by washing with water or, in the case of water-soluble product carbides, liquid ammonia, and carbide impurities may be removed by reaction with water followed by leaching the resulting oxide or hydroxide with dilute hydrochloric acid. The process is extensively exemplified using various carbon sources and metal sources.
