I-Pt-iridium wire iyingxube kanambambili esekwe kuplatinamu equkethe i-selenium. Kuyisixazululo esiqinile esiqhubekayo ekushiseni okuphezulu. Uma kupholiswe kancane ku-975~700 ºC, ukubola kwesigaba esiqinile kwenzeka, kodwa inqubo yokulinganisa yesigaba ihamba kancane kakhulu. Ingathuthukisa kakhulu ukumelana nokugqwala kweplatinamu ngenxa yokuguquguquka kwayo kalula kanye ne-oxidation. Kukhona i-Ptlr10, i-Ptlr20, i-Ptlr25, i-Ptlr30 namanye ama-alloys, anobunzima obuphezulu kanye nephuzu elincibilikayo eliphezulu, ukumelana nokugqwala okuphezulu kanye nokumelana okuphansi kokuxhumana, izinga lokugqwala kwamakhemikhali lingu-58% we-platinum ehlanzekile, kanti ukulahlekelwa kwesisindo se-oxidation ngu-2.8mg/g . Kuyinto yakudala yokuxhumana kagesi. Isetshenziselwa othintana nabo bokuthungela okuphezulu kwama-aero-engines, ukuthintana kukagesi kwama-relay anokuzwela okuphezulu nama-Wei motors; ama-potentiometer namabhulashi endandatho aqhubayo ezinzwa ezinembayo njengendiza, imicibisholo nama-gyroscopes
Isisetshenziswa:
Isetshenziswa kabanzi ezitshalweni zamakhemikhali, imicu, ama-spark plugs
