PT-iRidium xaim yog ib qho platinum-based binary alloy muaj Selenium. Nws yog kev daws teeb meem kev ua tiav ntawm cov kub. Thaum maj mam txias rau 975 ~ 700 ºC, khoom theem decomposition tshwm sim, tab sis theem sib npaug txheej txheem qeeb heev. Nws tuaj yeem txhim kho lub corrosion tsis kam ntawm platinum vim nws yooj yim volatilization thiab oxidation. Muaj PTLR10, PTLR20, PTLR20, PTLR30 thiab lwm yam kev nyuaj, cov tshuaj lom neeg tiv thaiv, thiab cov oxidation poob phaus yog 2.8mg / g. Nws yog cov khoom siv hluav taws xob classic. Siv rau cov neeg tiv tauj siab ntawm Aero-tshuab-tshuab, cov khoom siv hluav taws xob ntawm kev nthuav dav dav dav thiab WE WE WHI MOTORS; Potentiometers thiab conductive ntiv nplhaib txhuam ntawm precision sensors xws li aircraft, cuaj luaj thiab gyroscopes
Khoom siv:
Dav siv hauv cov nroj tsuag tshuaj, cov neeg ua kom zoo, ual ci plugs
