Iridium Sheet thiab Phaj piav qhia
Iridium yog ib qho khoom muaj nqis, nyiaj-dawb, tawv thiab nkig hlau. Nws tuaj yeem ua haujlwm ntawm qhov kub thiab txias ntawm 1,200 txog 1,500 degree (2,200℉ txog 2,700℉). Iridium yog ib qho ntawm cov khoom hnyav tshaj plaws hauv ntiaj teb. Nyob rau hauv lub xeev loj heev iridium yog xyaum insoluble nyob rau hauv acids thiab yog txawm tsis tawm tsam los ntawm aqua regia. Nws yog yaj nyob rau hauv concentrated hydrochloric acid nyob rau hauv lub xub ntiag ntawm sodium perchlorate ntawm 125 degree thiab 150 degree (257℉ thiab 302℉).
SSC yog tshwj xeeb hauv kev tsim Iridium ua cov ntawv thiab cov phaj hauv ntau qhov tuab thiab ntau thiab tsawg. Peb kuj muab platinum-iridium alloys nrog proportions ntawm 90 feem pua platinum / 10 feem pua iridium thiab 80 feem pua platinum / 20 feem pua iridium. SSC muag platinum-iridium alloys ua raws li ASTM B684 specification (xws li ASTM B 684-97). Cov alloys muaj cov tshuaj ruaj khov ntawm platinum thiab nce hardness. Thov hu rau peb kom paub meej ntxiv.
