Intambo yeplatinum-rhodium yi-alloy ye-platinum equlethe i-rhodium, esisisombululo esiqinileyo esiqhubekayo kubushushu obuphezulu. I-Rhodium yonyusa amandla obushushu, ukumelana ne-oxidation kunye nokumelana nokugqwala kwe-acid ye-alloy ukuya kwi-platinum. Kukho ii-alloys ezifana ne-PtRh5, PtRhl0, PtRhl3, PtRh30 kunye ne-PtRh40. Ii-alloys ezine-Rh engaphezulu kwe-20% azinyibiliki kwi-aqua regia. Zisetyenziswa kakhulu njengezixhobo ze-thermocouple, kuquka i-PtRhl0/Pt, PtRh13/Pt, njl.njl., ezisetyenziswa njengeentambo ze-thermocouple kwi-thermocouples, ukulinganisa ngokuthe ngqo okanye ukulawula ulwelo, umphunga kunye neegesi kuluhlu lwe-0-1800 ℃ kwiinkqubo ezahlukeneyo zemveliso zobushushu bomphezulu ophakathi nowomeleleyo.
Iingenelo: Ucingo lweplatinum rhodium luneengenelo zokuchaneka okuphezulu, uzinzo olungcono, indawo yokulinganisa ubushushu obubanzi, ubomi obude benkonzo kunye nomlinganiselo wobushushu obuphezulu kumda ophezulu kuthotho lwe-thermocouple. Lufanelekile kwi-oxidizing kunye ne-inert atmospheres, kwaye lungasetyenziswa nakwi-vacuum okwethutyana elifutshane, kodwa alufanelekanga ukunciphisa i-atmospheres okanye i-atmospheres equlethe isinyithi okanye umphunga ongengowesinyithi.
Iithermocouples zoshishino ziquka iplatinum-rhodium wire B uhlobo, uhlobo lwe-S, uhlobo lwe-R, iplatinum-rhodium thermocouple, ekwaziwa ngokuba yi-thermocouple yentsimbi exabisekileyo ebushushu obuphezulu, iplatinum-rhodium ineplatinum-rhodium enye (platinum-rhodium 10-platinum-rhodium) kunye neplatinum-rhodium ephindwe kabini (platinum-rhodium). I-Rhodium 30-Platinum Rhodium 6), zisetyenziswa njengezinzwa zokulinganisa ubushushu, zihlala zisetyenziswa kunye nezithumeli zobushushu, abalawuli kunye nezixhobo zokubonisa ukwenza inkqubo yolawulo lwenkqubo yokulinganisa okanye ukulawula ngokuthe ngqo 0- Amaqondo obushushu afana nolwelo, umphunga kunye nemidiya yegesi kunye neendawo eziqinileyo kuluhlu lwe-1800°C.
Amashishini asetyenziswayo ngala: intsimbi, ukuveliswa kombane, ipetroliyam, ishishini leekhemikhali, ifayibha yeglasi, ukutya, iglasi, amayeza, iiseramikhi, iintsimbi ezingezizo i-ferrous, unyango lobushushu, i-aerospace, i-powder metallurgy, i-carbon, i-coking, i-printing kunye ne-dyeing kunye nezinye phantse zonke iindawo zoshishino.
