20140185190 | METHOD FOR PRODUCING ELECTROLYTIC CAPACITORS FROM VALVE METAL POWDERS - A process for producing an anode for an electrolytic capacitor includes pressing a tantalum powder around a tantalum wire, a tantalum ribbon, or a tantalum sheet to form a pressed body. The pressed body is sintered to form a porous sintered body. The porous sintered body is cooled to form a cooled porous sintered body. The cooled porous sintered body is treated with at least one oxidant comprising at least one of a gaseous oxidant and a liquid oxidant to form a treated sintered body. The treated sintered body is anodically oxidized in an electrolyte to form a dielectric layer. | 07-03-2014 |
20150292081 | HIGH PURITY REFRACTORY METAL POWDERS AND THEIR USE IN SPUTTERING TARGETS WHICH MAY HAVE RANDOM TEXTURE - A method for making a sputtering target including steps of encapsulating and hot isostatically pressing at least one mass of metal powder (e.g., tantalum), having a particle size ranging from about 10 to about 1000 μm, with at least about 10 percent by weight of particles having a particle size greater than about 150 μm (for example, about 29 to about 56 percent (e.g., about 35 to about 47 percent) by weight of the particles in the at least one mass of metal powder having a particle size that is larger than 150 microns, but below about 250 μm), for defining at least a portion of a sputtering target body, having an essentially theoretical random and substantially uniform crystallographic texture. | 10-15-2015 |

20160064150 | METHOD FOR PRODUCING LOW-OXYGEN VALVE-METAL SINTERED BODIES HAVING A LARGE SURFACE AREA - A process for producing a sintered body includes pressing a powder comprising or consisting of at least one valve metal so as to provide a pellet, providing the pellet together with a reducing agent so that the pellet is not in a direct contact with and does not come into a direct contact with the reducing agent, heating so that the powder in the pellet is sintered to form a sintered body, an oxygen content of the at least one valve metal within the sintered body is simultaneously reduced, and the reducing agent is oxidized to an oxidized reducing agent, and removing the oxidized reducing agent with at least one mineral acid. | 03-03-2016 |
