Platinum-rhodium waya shine tushen platinum mai ƙunshe da rhodium da ke ƙunshe da alloy na binaryar, wanda shine ci gaba da ingantaccen bayani a yanayin zafi. Rhodium yana haɓaka yuwuwar thermoelectric, juriya na iskar shaka da juriyar lalata acid na gami zuwa platinum. Akwai gami kamar PtRh5, PtRhl0, PtRhl3, PtRh30 da PtRh40. Alloys tare da fiye da 20% Rh ba su iya narkewa a cikin ruwa. Yafi amfani da matsayin thermocouple kayan, ciki har da PtRhl0 / Pt, PtRh13 / Pt, da dai sauransu, amfani da matsayin thermocouple wayoyi a cikin thermocouples, kai tsaye auna ko sarrafa ruwaye, tururi da gas a cikin kewayon 0-1800 ℃ a daban-daban samar matakai zafin jiki na matsakaici. da m surface.
Abũbuwan amfãni: Platinum rhodium waya yana da abũbuwan amfãni daga mafi girman daidaito, mafi kyaun kwanciyar hankali, fadi da zafin jiki wurin aunawa, tsawon sabis rayuwa da high zafin jiki ma'auni babba a cikin thermocouple jerin. Ya dace da oxidizing da inert yanayi, kuma ana iya amfani da shi a cikin vacuum na ɗan gajeren lokaci, amma bai dace da rage yanayi ko yanayin da ke dauke da ƙarfe ko tururin ƙarfe ba. .
Ma'aunin thermocouples na masana'antu sun haɗa da nau'in platinum-rhodium waya B nau'in, nau'in S, nau'in R, nau'in platinum-rhodium thermocouple, wanda kuma aka sani da babban zafin jiki mai daraja na ƙarfe mai zafi, platinum-rhodium yana da platinum-rhodium ɗaya (platinum-rhodium 10-platinum-rhodium) da Platinum-rhodium biyu (platinum-rhodium). Rhodium 30-Platinum Rhodium 6), ana amfani da su azaman na'urori masu auna zafin jiki, yawanci ana amfani dasu tare da masu watsa zafin jiki, masu sarrafawa da kayan nuni don samar da tsarin sarrafa tsari don aunawa ko sarrafa kai tsaye da m saman a cikin kewayon 1800 ° C.
Masana'antun da ake amfani da su sune: karfe, samar da wutar lantarki, man fetur, masana'antun sinadarai, fiber gilashi, abinci, gilashi, magunguna, yumbu, karafa marasa ƙarfe, maganin zafi, sararin samaniya, ƙwayar foda, carbon, coking, bugu da rini da sauran kusan duka. filayen masana'antu.
