Wayar Tungsten: Ana amfani da ita don yin tungsten-rhodium thermocouples da kawuna masu haɗawa da sauri, wayoyi masu haɗawa da sapphire, da na'urorin lantarki don manyan lasers. Hakanan ana amfani da shi don yin filaments masu inganci da bututun cathodes. A 2005, Multi-manufa tungsten-rhenium gami waya ci gaba da mu kamfanin aka jera a matsayin kasa key sabon samfurin da Ma'aikatar Kimiyya da Fasaha.
Tungsten-rhenium thermocouple waya yana da wurin narkewa na 3120-3360 ° C kuma ana iya amfani dashi har zuwa 3000 ° C. Shi ne mafi juriya karfe thermocouple. Yana da abũbuwan amfãni na kyakkyawar alakar layi tsakanin zafin jiki da ƙarfin lantarki, ingantaccen yanayin zafi da ƙarancin farashi. An daidaita shi da kayan aikin nuni. Ana auna zafin da za a iya auna kai tsaye a halin yanzu a yanayin zafi sama da 1600 ° C. Ana yawan amfani da hanyar da ba ta sadarwa ba. Duk da haka, kuskuren wannan hanya yana da girma. Misali, zafin lamba na iya auna ainihin zafin jiki daidai. A cikin ma'aunin zafi mai zafi, ma'aunin ma'aunin ma'aunin ƙarfe masu daraja (platinum-rhodium thermocouples) suna da tsada kuma matsakaicin zafin jiki zai iya zama ƙasa da 1800 ° C, yayin da tungsten-rhodium thermocouples ba kawai suna da iyakar zafin jiki ba amma har ma da kwanciyar hankali, sabili da haka, tungsten- rhodium thermocouples Ana amfani dashi sosai a cikin ƙarfe, kayan gini, sararin samaniya, jiragen sama da masana'antar makamashin nukiliya. Matsakaicin zafinsa na aiki zai iya kaiwa 2800 ° C, amma fiye da 2300 ° C, bayanan sun tarwatse. Tungsten-rhenium thermocouples suma suna da oxidizable sosai, don haka ana iya amfani da su a cikin sarari, raguwa, ko yanayi mara kyau a yanayin zafi daga 0 zuwa 2300 ° C. Hakanan za'a iya amfani da ma'auratan Tungsten bismuth tare da bututun kariya na musamman na dogon lokaci a cikin yanayi mai oxidizing a 1600 ° C. Suna da arha fiye da ma'aunin thermocouples na platinum-rhodium kuma ba za a iya amfani da su a cikin yanayin da ke ɗauke da carbon (kamar a cikin yanayi mai ɗauke da hydrocarbon). yanayin zafi ya wuce 1200 ° C yana ƙarƙashin lalata). Tungsten ko tungsten ruthenium yana ƙoƙarin samar da barga carbide a cikin yanayi mai ɗauke da carbon, ta yadda hankalinsa ya ragu kuma yana haifar da karaya, kuma a gaban hydrogen, carbonization yana haɓaka. Kamfanin ya ƙware a cikin samar da anti-oxidation tungsten-rhodium thermocouples. Madaidaicin zafin jiki shine 0-1500 ° C. Tsarin shi ne bututun kariya mai Layer biyu ko mai Layer uku (ba a saba amfani da shi ba). Bututun kariya na waje na tsarin bututun kariya biyu shine bututu corundum mai tsafta mai tsafta. Bututun kariya na ciki shine bututun silicide na molybdenum, kuma bututun kariya na waje na hannun hannu uku shine bututun siliki carbide da aka sake sake shi ko bututun corundum mai tsafta na musamman, bututun tsakiya da bututun kariya na ciki iri daya ne da nau'in bututu biyu, kuma kayan cika bututu abu ne mai tsananin zafin jiki (yana iya zama na dogon lokaci ana amfani da shi ƙasa da 1800 ° C), rufewa da rufewar sanyi (ana iya amfani da mannen rufewa a yanayin zafi ƙasa 300 ° C na dogon lokaci) don tabbatar da babu. sauran oxygen a cikin tube. Wannan samfurin ya dace da amfani a cikin injin daskarewa, raguwa da sauran iskar gas (0 ~ 1650 ° C) Ma'aunin zafin jiki mai kyau a cikin yanayin oxidizing shine 0 zuwa 1500 ° C. Tsawon lokaci: ≥180 s
