20080206090 | IRIDIUM-BASED ALLOY WITH HIGH HEAT RESISTANCE AND HIGH STRENGTH AND PROCESS FOR PRODUCING THE SAME - An iridium-based alloy which has Ll | 08-28-2008 |
20080213123 | Doped Iridium with Improved High-Temperature Properties - The invention relates to an iridium alloy of at least 85% by weight iridium, at least 0.005% by weight molybdenum, 0.001 to 0.6% by weight hafnium and, if necessary, rhenium, the sum of molybdenum and hafnium being between 0.002 and 1.2% by weight, and to a process for the production of an iridium alloy, an IrMo and an IrHf master alloy, respectively, being produced in the electric arc and immersed into an iridium melt, if necessary together with Re. | 09-04-2008 |
20090317289 | PROCESS FOR PRODUCING METAL NANOPARTICLE AND METAL NANOPARTICLE PRODUCED BY THE PROCESS - The present invention has an object of providing a single-stage production method that enables the production of ultra fine metal nanoparticles and ordered alloy nanoparticles within solution. | 12-24-2009 |
20100111751 | METHOD FOR THIOSULFATE LEACHING OF PRECIOUS METAL-CONTAINING MATERIALS - Processes are provided for recovering precious metals from refractory materials using thiosulfate lixiviants. The processes can employ heap leaching or lixiviants that include one or more blinding agents. | 05-06-2010 |
20100239453 | IRIDIUM ALLOY EXCELLENT IN HARDNESS, WORKABILITY AND ANTI-CONTAMINATION PROPERTIES - The present invention provides an iridium alloy suitable for a wire rod for probe pins, with zirconium as an additive element contained as an essential element and with aluminum and/or copper further added. In this iridium alloy, the additive concentration of zirconium is 100 to 500 ppm and the total additive concentration of aluminum and copper is 10 to 500 ppm. The present invention will be able to meet such requirements placed on a material for probe pins as that further miniaturization thereof would be demanded in the future and that use environment thereof becomes severe. | 09-23-2010 |
20100329922 | INCREASING THE STRENGTH OF IRIDIUM, RHODIUM, AND ALLOYS THEREOF - The addition of 0.5 to 30 ppm boron and 0.5 to 20 ppm calcium to iridium and the Zr- and Hf-free alloys thereof and rhodium and the Zr- and Hf-free alloys thereof surprisingly increases the creep rupture strength at high temperatures, in particular around 1,800° C. | 12-30-2010 |
