摘要： 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.

摘要： A metallothermy method includes continuously withdrawing an ingot of a metal product such as uranium or a uranium alloy as it is formed from an oxide or salt of the metal. The method employs upper and lower communicating crucibles. The upper crucible contains a layer of reducing medium floating on a solvent medium. The metal oxide or metal salt is reduced as it is introduced into the layer reducing medium to form metal particles and slag. The settling metal is melted by further induction heating, collected in the lower crucible and withdrawn. The slag is absorbed by the solvent medium which is regenerated with the use of electrolysis.

摘要： The invention relates to a method to be used in producing easily volatile metals from their sulfides. The method employs two closely connected furnaces, a reduction furnace and a converter, which are operated at normal pressure, so that the material transfer therebetween is arranged to be carried out continuously at normal pressure through the channels provided in between the furnaces. As a result of chemical reactions taking place in the furnaces, the hydrostatic pressure in the furnaces changes, and the circulations caused by these changes through the channels at the same time bring about recycling of the sulfide matte needed in the process from the reduction furnace to the converter and the recycling of the molten metal from the converter to the reduction furnace.

Upon heating in an inert atmosphere at a temperature greater than the melting point of the electrolyte, the higher valence titanium is reduced by aluminum metal to form divalent titanium. Titanium-aluminum alloys of up to 50 atomic percent titanium can then be deposited from the electrolyte.

摘要： High-purity metallic chromium is produced by a method of initially preparing a mixture of chromium oxide, aluminum, carbon and an easily sulfidable metallic powder, and subsequently providing a thermite-reaction with the mixture to produce thermite-crude metallic chromium and a solid solution of carbon and easily sulfidable metal. Residual impurities in the thermite-crude metallic chromium are subsequently removed by heat treating the crude metallic chromium. This method produces high-purity metallic chromium advantageous for preparing corrosion and heat resistant chromium-containing alloys.
