Platinum-rhodium terata ke platinum-based rhodium-containing binary alloy, e leng tharollo e tsitsitseng e tsitsitseng mocheso o phahameng. Rhodium e eketsa bokhoni ba thermoelectric, khanyetso ea oxidation le ho hanyetsa kutu ea acid ea alloy ho platinum. Ho na le li-alloys tse kang PtRh5, PtRhl0, PtRhl3, PtRh30 le PtRh40. Li-alloys tse nang le Rh e fetang 20% ​​ha li qhibilihe ka har'a aqua regia. Haholo-holo e sebelisoa e le thepa ea thermocouple, ho kenyeletsoa PtRhl0/Pt, PtRh13/Pt, joalo-joalo, e sebelisoang e le lithapo tsa thermocouple ho thermocouples, ho lekanya ka kotloloho kapa ho laola maro, mouoane le likhase tsa 0-1800 ℃ lits'ebetsong tse fapaneng tsa tlhahiso ea mocheso oa mahareng. le bokahodimo bo tiileng.
Melemo: Mohala oa Platinum rhodium o na le melemo ea ho nepahala ho phahameng ka ho fetisisa, botsitso bo botle ka ho fetisisa, sebaka se pharaletseng sa tekanyo ea mocheso, bophelo bo bolelele ba tšebeletso le tekanyo e phahameng ea mocheso letotong la thermocouple. E loketse oxidizing le inert atmospheres, hape e ka sebelisoa ka vacuum ka nako e khutšoanyane, empa ha e tšoanelehe bakeng sa ho fokotsa sepakapaka kapa sepakapaka se nang le mouoane oa tšepe kapa o seng oa tšepe. .
Li-thermocouple tsa indasteri li kenyelletsa terata ea platinum-rhodium mofuta oa B, mofuta oa S, mofuta oa R, platinum-rhodium thermocouple, eo hape e tsejoang e le mocheso o phahameng oa mocheso oa tšepe ea bohlokoa, platinum-rhodium e na le platinum-rhodium e le 'ngoe (platinum-rhodium 10-platinum-rhodium) le platinum-rhodium e habeli (platinum-rhodium). Rhodium 30-Platinum Rhodium 6), li sebelisoa e le li-sensor tsa tekanyo ea mocheso, hangata li sebelisoa hammoho le li-transmitters tsa mocheso, balaoli le lisebelisoa tsa pontšo ho theha mokhoa oa ho laola mokhoa oa ho lekanya kapa ho laola ka ho toba 0- Thempereichara e kang maro, mouoane le mecha ea litaba ea khase. le libaka tse tiileng sebakeng sa 1800°C.
Liindasteri tse sebelisoang ke: tšepe, tlhahiso ea matla, petroleum, indasteri ea lik'hemik'hale, fiber ea khalase, lijo, khalase, meriana, lirafshoa, litšepe tse se nang ferrous, phekolo ea mocheso, sebaka sa sefofane, metallurgy ea phofo, carbon, coking, khatiso le ho daea le tse ling tse ngata. masimo a indasteri.
