The process of the present invention has the advantages of: simple operation, the tantalum and/or niobium powders obtained have high surface area, high purity, good flowability, therefore are particularly suitable for manufacturing electrolytic capacitors.Type: ApplicationFiled: September 30, 2002Publication date: June 19, 2003Inventors: Jilin He, Luntao Pan, Ningfeng Yuan, Xiaoli Wen, Xingbang Li

Publication number: 20030110891Abstract: The invention concerns a method for iron reduction to make sponge iron which consists in: depositing a feed of iron ore on a grate and moving the grate so as to cause the feed to pass in at least three different zones; inputting gases, called input gases into one or several zones, including a hot gaseous carbonaceous reducing agent, and forcing said input gases through the ore located on the grate; and capturing the gases resulting from said forced passage, called output gases. The passage of the input gases brings the ore to a temperature ranging between 850° C. and 1300° C.; maintaining said feed at said temperature until an iron ore metallizing rate ranging between 60% and 100% is obtained. The feed deposited on the grate consists of either iron ore calibrated between 5 mm and 40 mm, or iron ore pellets having a diameter ranging between 5 mm and 20 mm, or iron ore granules of size between 2 mm and 10 mm, and the thickness of the deposited layer ranges between 150 mm and 600 mm.Type: ApplicationFiled: November 7, 2002Publication date: June 19, 2003Inventors: Bernard Vanderheyden, Rene Munnix

Publication number: 20030110892Abstract: In devices used for the direct conversion of heat into electricity, or vice versa, known in the art as thermoelectric power generators, thermoelectric refrigerators and thermoelectric heat pumps, the efficiency of energy conversion and/or coefficient of performance have been considerably lower than those of conventional reciprocating or rotary, heat engines and/or vapor-compression systems, employing certain refrigerants. The energy conversion efficiency of power generating devices, for example, aside from the hot and cold junction temperatures, also depends on a parameter known in the art as the thermoelectric figure of merit Z=S2&sgr;/k, where S is the thermoelectric power, &sgr; is the electrical conductivity and k is the thermal conductivity, of the material that constitutes the p-type, and/or n-type, thermoelements, or branches, of the said devices.Type: ApplicationFiled: September 5, 2002Publication date: June 19, 2003Inventor: Michael C.
