Siliga Pt-iridium waa daawaha laba-jibbaaran ee ku salaysan platinum oo ka kooban selenium. Waa xal adag oo joogto ah heerkulka sare. Marka si tartiib tartiib ah loo qaboojiyo 975 ~ 700 ºC, burburka wejiga adag ayaa dhacaya, laakiin habka dheellitirka wajigu si tartiib tartiib ah ayuu u socdaa. Waxay si weyn u wanaajin kartaa iska caabbinta daxalka ee platinum sababtoo ah isbeddelka fudud iyo oksaydhka. Waxaa jira Ptlr10, Ptlr20, Ptlr25, Ptlr30 iyo Alloys kale, oo leh qallafsanaan sare iyo barta dhalaalaysa sare, caabbinta daxalka sare iyo iska caabin hoose, heerka daxalka kiimikada waa 58% of platinum saafi ah, iyo oxidation miisaan lumis waa 2.8mg/g . Waa qalab xiriir koronto oo caadi ah. Loo isticmaalo xidhiidhada shidida sare ee matoorada aero-matoorada, xidhiidhada korantada ee relays oo leh dareen sare iyo matoorada Wei; potentiometers iyo burushyada giraanta gacanta ka qaada ee dareemayaasha saxda ah sida diyaaradaha, gantaalada iyo gyroscopes
Si weyn loogu isticmaalo dhirta kiimikaad, fiilooyin, dhinbiilyaal
