Patent number: 7445658Abstract: A method of producing a non-metal element or a metal or an alloy thereof from a halide or mixtures thereof. The halide or mixtures thereof are contacted with a stream of liquid alkali metal or alkaline earth metal or mixtures thereof in sufficient quantity to convert the halide to the non-metal or the metal or alloy and to maintain the temperature of the reactants at a temperature lower than the lesser of the boiling point of the alkali or alkaline earth metal at atmospheric pressure or the sintering temperature of the produced non-metal or metal or alloy. A continuous method is disclosed, particularly applicable to titanium.Type: GrantFiled: April 19, 2002Date of Patent: November 4, 2008Assignee: UChicago Argonne, LLCInventors: Donn Reynolds Armstrong, Stanley R. Borys, Richard P. Anderson

Patent number: 6861038Abstract: A method of continuously producing a non-oxide ceramic formed of a metal constituent and a non-metal constituent. A salt of the metal constituent and a compound of the non-metal constituent and a compound of the non-metal constituent are introduced into a liquid alkali metal or a liquid alkaline earth metal or mixtures to react the constituents substantially submerged in the liquid metal to form ceramic particles. The liquid metal is present in excess of the stoichiometric amount necessary to convert the constituents into ceramic particles to absorb the heat of reaction to maintain the temperature of the ceramic particles below the sintering temperature. Ceramic particles made by the method are part of the invention.Type: GrantFiled: September 3, 2003Date of Patent: March 1, 2005Assignee: International Titanium Powder, LLC.Inventors: Donn Reynolds Armstrong, Stanley S. Borys, Richard Paul Anderson
