| titleOfInvention | Process for producing very pure platinum materials, semifinished parts and foils dispersion-reinforced with y2o3 |
| abstract | Process for producing very pure platinum materials dispersion-reinforced with Y2O3 and having high strength and extensibility, even in the temperature range > 800°C, from platinum powder by mechanical alloying, which comprises the process steps - preparing platinum powder of high purity and low particle size of from 2 to 10 µm, - introducing and dispersing Y2O3 particles < 1 µm in the platinum powder by milling in a platinum vessel using milling media of zirconium oxide, - degassing the milled product under a vacuum of better than 10-3 mbar and with an increase in tem-perature to at least 1200°C in a platinum capsule for a period of up to 48 hours, - gastight welding of the evacuated capsule and hot isostatic pressing at 1350°C and 200 MPa to give blocks of compact dispersion-reinforced platinum having a density of 100 %, - producing semi-finished parts and foils from these dispersion-reinforced platinum materials, these parts and foils having - a platinum purity of at least 99.95 %, - a tensile strength Rm from 300 to 350 MPa, - an extensibility A of 15 - 25 % and a - grain stability up to 1400°C. |
