    摘要: An apparatus for carrying out chlorinating reactions when extracting metalsuch as titanium, zirconium or the like during the extraction of uranium and thorium during the reprocessing of burned-off fuel and/or breeder elements for core reactors and during the purification of coal and graphite. The device comprises a shaft or blast furnace which is heated by a direct flow of current and while being coaxially surrounded by a mantle or shell communicates through a connection or adapter piece with a subsequent condenser of graphite. The device according to the present invention is characterized primarily in that the shell of the furnace and the adapter piece connecting the furnace with the condenser are made of graphite. The shell of the furnace, the condenser and the adapter piece connecting the shell with the condenser are arranged within a steel casing designed in a gas-tight manner.

    摘要: Ores containing oxides of Titanium, Zirconium and Hafnium metals are reduced by mixing them in the powdered state with a base hydroxide of one of the Classes I-A or II-A metals of the periodic table of elements and either sugar or starch, mixing them well, then heating the mixture until ignition begins and maintaining the necessary heat until ignition is finished. The remaining residue is then flushed and boiled with water to remove waste chemicals, leached with hydrocarbon solvents, hydrochloric acid, again boiled with water, flushed, dryed, and then smelted to Class IV-B metal powder or ingot.

    摘要: Ores containing oxides of Titanium, Zirconium and Hafnium metals are reduced by mixing them in the powdered state with a chemical solution formula consisting primarily of phosphoric acid, zinc oxide, and a sulfated surfactant. Calcium carbonate is added to the solution as a catalyst and the mixture is brought to a boil, allowing the volatile materials to vaporize out of the mixture so as to provide either pliable or hard formed residue material. Sodium bicarbonate and water are added to the pliable which reacts chemically with waste chemicals, then is decanted and flushed with water, cleansing agents, etc. and dried. Powder may then be subjected to the plasma arc furnace so as to provide commercially pure and semi-pure powder, sponge-like ingot, or metallized upon other metal surfaces. Or the powder may be leached and cleansed of the phosphide contaminants within it and then smelted. This is accomplished by boiling it within hydroxide bases, molten halogen salts, or burning it within a mixture of hydroxide bases and sugar. Resultant material then sets in repose with added water, boiled, flushed, reacted with hydrochloric acid, again boiled with water, cleansed and rinsed with water, then dried, screened and smelted. Smelting is accomplished by plasma arc furnaces, vacuum-inert furnaces containing molten metal of the Ia or IIa Periodic Table Class groups, or vacuuminert furnaces operating at the respective melting points of the metal. The hard formed residue is pulverized to small particle size, boiled within hydroxide bases, molten halogen salts, or burned within a mixture of hydroxide bases and sugar. Resultant material then stes in repose with added water, boiled, flushed, reacted with hydrochloric acid, again boiled with water, cleansed and rinsed with water, then dried, screened and smelted. Smelting is accomplished by plasma arc furnaces, vacuum-inert furnaces containing molten metal of the Ia or IIa Periodic Table Class groups, or vacuum-inert furnaces operating at the respective melting points of the metal.

    摘要: A PROCESS FOR THE MANUFACTURE OF TITANIUM FROM TITANIUM TETRACHLORIDE BY REDUCTION WITH SODIUM, IN WHICH A PARTIALLY REDUCED MATERIAL PRINCIPALLY CORRESPONDING TO NA2TICL4 IS CONTINUOUSLY FORMED, IS IMPROVED BY CONTINUOUSLY MIXING THE PARTIALLY REDUCED MATERIAL WITH SODIUM AT A TEMPERATURE BELOW ABOUT 200*C. SO AS TO FORM AN INTERMEDIATE MATERIAL CORRESPONDING TO AT LEAST 15% BY WEIGHT NA3TICL4, COMPACTING THE INTERMEDIATE MATERIAL AT A TEMPERATURE OF LESS THAN 100*C. TO FORM A CONTINUOUS ROD OF THE COMPOSITE MATERIAL WITHOUT SUBSTANTIAL FURTHER REDUCTION OF THE TITANIUM CHLORIDE CONTENT THEREOF AND CONTINUOUSLY HEATING THE ROD FORMED AT TEMTERATURES ABOUT 800*C. TO COMPLETE REDUCTION OF TITANIUM CHLORIDE COMPONENT THEREOF, TO EFFECT SINTERING OF THE RESULTING TITANIUM METAL, AND TTO SIMULTANEOUSLY MELT THE SALT BY-PRODUCT AND THEREBY FACILITATE SEPARATION AND REMOVAL OF THE SALT FROM THE ROD-SHAPED, SINTERED TITANIUM METAL PRODUCT.
