摘要： The present invention relates to an apparatus for obtaining high purity ruthenium metal without the need for high temperature processing, expensive reagents, complex series of wet processes, or expensive equipment. According to the present invention, a gas stream including ozone (O3) is brought into contact with a ruthenium source in one or more reaction vessels. The ozone reacts with the ruthenium source to form ruthenium tetraoxide (RuO4), a compound that is a gas at the reaction conditions. The ruthenium tetraoxide, along with unreacted ozone and the remainder of the gas stream is then fed into a collection vessel where a major portion of the m gaseous ruthenium tetraoxide is thermally reduced to form ruthenium dioxide (RuO2) deposits within the collection vessel. The deposited ruthenium dioxide is then reduced to produce highly pure ruthenium metal.

摘要： Impurities are extracted from a thin-film device structure based on mercury, cadmium, zinc, and/or tellurium, such as HgCdTe, CdTe, CdZnTe, or HgCdZnTe. The impurities are extracted by furnishing a sink medium comprising molten bismuth, and contacting the contaminated structure to the sink medium for a period of time sufficiently long that impurities diffuse out of the structure and into the bismuth for removal. The molten bismuth may additionally contain small amounts of one or more of the major components of the structure (mercury, cadmium, zinc, and/or tellurium) to inhibit loss of these elements from the structure.

摘要： The present invention is directed to an apparatus and method for recovering the group III elemental component of a group III-V material waste material. The method includes heating, under a reduced pressure, solid waste materials which contain group III-V material to cause the group III-V material to separate into a group III element and a group V element vapor; drawing off the group V element vapor; condensing the group V element vapor to produce a condensed group V element solid; and zone refining the group III element to produce a purified group III element. The apparatus is designed to carry out this method in the plant which manufactures the group III-V waste material.

摘要： Superalloy articles are made more oxidation resistant by a process which includes heat treating the article in the presence of foreign chemical species, at a temperature at which the foreign chemical species reacts with and modifies any oxide film present on the article surface. The heat treatment is best carried out at a temperature above the gamma prime solvus temperature of the article and below the incipient melting temperature of the article. Alternatively, the heat treatment may be carried out within the range defined by the incipient melting temperature of the article and about 150.degree. C. below the incipient melting temperature of the article. At such temperatures the foreign chemical species reacts with and modifies the oxide film on the article surface. Sulfur is then able to diffuse through such modified film, and a more oxidation resistant component is produced.

摘要： Superalloy articles are made more oxidation resistant by a process which includes heating the article in an environment having a reduced pressure of inert gas and a low partial pressure of oxygen to a temperature at which the sulfur in the article diffuses out. The heat treatment is best carried out at a temperature within the range defined by the incipient melting temperature of the article and about 150.degree. C. below the incipient melting temperature of the article. Alternatively, the heat treatment may be carried out at a temperature above the gamma prime solvus temperature of the article and below the incipient melting temperature of the article. At such temperatures, sulfur readily diffuses out of the article, and a more oxidation resistant component is produced.

摘要： A method of refining the microstructure of metals which undergo a phase transformation at high temperatures by diffusing a solute material into the metal at a temperature below the normal transformation temperature. The solute induces the phase transformation and removal of the solute at a temperature near the transformation temperature reverses the transformation. These phase transformations refine the microstructure of the metal so treated. The method is particularly useful to Group IVB metals i.e. Zr, Hf and Ti.

摘要： A process is disclosed for producing silicon having a purity 99.999% or better which comprises contacting solid silicon at a temperature slightly below the melting point of silicon with a molten purifying agent which does not appreciably react with silicon to cause the impurities in the silicon to enter the molten material. After cooling, the purified silicon is separated from the purifying agent and the impurities therein by leaching.
