Bututun Sapphire a cikin Kariyar Thermocouple
Thermocouples sune mahimman na'urori masu auna zafin jiki da ake amfani da su a cikin masana'antu da suka kama daga sararin samaniya da ƙarfe zuwa ƙirƙira na semiconductor da sarrafa sinadarai. Koyaya, thermocouples kayan aiki ne masu mahimmanci waɗanda zasu iya raguwa da sauri lokacin da aka fallasa su kai tsaye ga iskar gas, mahalli na plasma, ko saurin dumama/sanyi hawan keke. Don hana waɗannan al'amura, bututun sapphire suna zama madaidaicin sheaths masu kariya ga ma'aunin zafi da sanyio.
Ƙarƙashin zafin jiki na sapphire yana tabbatar da sauri da daidaitaccen canja wurin zafi zuwa thermocouple a cikin bututu, yana ba da damar kulawa da zafin jiki na lokaci-lokaci yayin da yake kare firikwensin daga abubuwa masu lalata, lalata injiniyoyi, da girgizar zafi. Wannan ma'auni na rufewa da sarrafawa yana sanya bututun sapphire da suka dace da kariya ta thermocouple a cikin mahalli mara kyau.
Bugu da kari, rashin kuzarin sinadarai na sapphire yana hana duk wani gurɓata yanayin tsarin. Wannan yana da mahimmanci musamman a aikace-aikace masu tsafta kamar sarrafa wafer semiconductor, tsarin haifuwa na likitanci, ko ɗakuna masu zafi. Rashin amsawa tsakanin sapphire da sinadarai masu haɗari kamar plasma fluorine, hydrochloric acid, ko narkakken karafa yana tabbatar da amincin tsarin duka da daidaiton aunawa.
Bugu da ƙari, bututun sapphire suna da juriya sosai don sawa kuma ba sa ƙasƙantar da su a cikin dogon lokaci zuwa ga barbashi masu ƙarfi ko zafin hasken UV/IR. Wannan ƙarfin yana ƙara tsawon rayuwar na'urori masu auna firikwensin thermocouple, yana rage farashin kulawa da raguwar tsarin.
