ʻO ka uea Platinum-rhodium he mea paʻa paʻa paʻa paʻa i ke kiʻekiʻe wela. Hoʻonui ʻo Rhodium i ka hiki ke thermoelectric, pale ʻana i ka oxidation a me ke kūpaʻa ʻana o ka ʻakika o ka alloy i ka platinum. Loaʻa nā ʻāpana e like me PtRh5, PtRhl0, PtRhl3, PtRh30 a me PtRh40. ʻAʻole hiki ke hoʻoheheʻe ʻia nā huila me ka 20% Rh i loko o ka aqua regia. Hoʻohana nui ʻia e like me nā mea thermocouple, me ka PtRhl0/Pt, PtRh13/Pt, a me nā mea ʻē aʻe, i hoʻohana ʻia e like me nā uea thermocouple i nā thermocouple, e ana pololei a hoʻopaʻa i nā wai, ka mahu a me nā kinoea i loko o ka laulā o 0-1800 ℃ i nā kaʻina hana like ʻole ka mahana o ka medium. a me ka ʻili paʻa.
Pōmaikaʻi: Platinum rhodium uea i nā pono o ka mea kiʻekiʻe loa pololei, ka maikai paʻa, akea wela ana wahi, lōʻihi lawelawe ola a me ke kiʻekiʻe wela ana palena palena luna ma ka thermocouple moʻo. He kūpono ia no ka oxidizing a me ka inert atmospheres, a hiki ke hoʻohana ʻia i loko o ka vacuum no ka manawa pōkole, akā ʻaʻole kūpono ia no ka hoʻohaʻahaʻa ʻana i nā lewa a i ʻole nā ​​​​wela e loaʻa i nā metala a i ʻole nā ​​mea hao. .
ʻO nā thermocouple ʻoihana he ʻano platinum-rhodium uea B ʻano, ʻano S, ʻano R, platinum-rhodium thermocouple, i ʻike ʻia he thermocouple metala makamae kiʻekiʻe, platinum-rhodium he platinum-rhodium hoʻokahi (platinum-rhodium 10-platinum-rhodium) a pālua platinum-rhodium (platinum-rhodium). ʻO Rhodium 30-Platinum Rhodium 6), hoʻohana ʻia lākou e like me nā ʻike ana wela, hoʻohana pinepine ʻia me nā mea hoʻouna wela, nā mea hoʻoponopono a me nā mea hōʻikeʻike e hana i kahi ʻōnaehana kaʻina hana e ana pololei a hoʻomalu paha i ka 0- Nā wela e like me nā wai, nā mahu a me nā media kinoea. a me nā ʻili paʻa ma ka laulā o 1800°C.
ʻO nā ʻoihana i hoʻohana ʻia: ke kila, ka hana mana, ka ʻaila, ka ʻoihana kemika, ka fiber aniani, ka meaʻai, ke aniani, ka lāʻau lapaʻau, ka seramika, nā metala non-ferrous, ka wela wela, ka aerospace, ka pauka metallurgy, carbon, coking, paʻi ʻana a me nā mea ʻē aʻe. kahua ʻoihana.
