Lapho i-tungsten ishisa, ibonisa izinto eziningi ezithakazelisayo.I-Tungsten inezinga eliphezulu lokuncibilika lazo zonke izinsimbi ezimsulwa, ngaphezu kuka-3,400 degrees Celsius (6,192 degrees Fahrenheit).Lokhu kusho ukuthi ingakwazi ukumelana namazinga okushisa aphakeme kakhulu ngaphandle kokuncibilika, okuyenza ibe into efanelekile yohlelo lokusebenza oludinga ukumelana nezinga lokushisa eliphezulu, njengemicu ye-incandescent light bulb filaments,izakhi zokushisa, nokunye ukusetshenziswa kwezimboni.

Emazingeni okushisa aphezulu, i-tungsten ibuye imelane kakhulu nokugqwala, iyenze ifanelekele ukusetshenziswa ezindaweni lapho ezinye izinsimbi zingehlisa khona.Ngaphezu kwalokho, i-tungsten ine-coefficient ephansi kakhulu yokunwetshwa kwe-thermal, okusho ukuthi ayinwebi noma ayinciphisi kakhulu uma ishisisiwe noma ipholile, okuyenza isebenziseke ezinhlelweni ezidinga ukuqina kobukhulu emazingeni okushisa aphezulu. Sekukonke, uma i-tungsten ishisa, igcina ukwakheka kwayo. ubuqotho futhi ikhombisa izakhiwo ezihlukile eziyenza ibe yigugu ngokwedlulele ezinhlelweni eziningi ezisezingeni lokushisa eliphezulu.

Intambo ye-Tungsten iyinto evame ukusetshenziswa emkhakheni wezinto zikagesi, izibani, njll. Ingase yande ngenxa yethonya lokushisa eliphezulu ngesikhathi sokusetshenziswa isikhathi eside.Ucingo lwe-Tungsten lunwetshwa futhi lufinyezwe ngesikhathi sokushintsha kwezinga lokushisa, okunqunywa izici zalo ezibonakalayo.Lapho izinga lokushisa likhuphuka, ukunyakaza okushisayo kwamangqamuzana ocingo lwe-tungsten kuyanda, ukukhangana kwe-interatomic kuba buthaka, okuholela ekushintsheni okuncane kobude bocingo lwe-tungsten, okungukuthi, kwenzeka into yokwandisa.

Ukunwetshwa kocingo lwe-tungsten kuhlobene ngokuqondile nezinga lokushisa, okungukuthi, njengoba izinga lokushisa likhuphuka, ukunwetshwa kocingo lwe-tungsten nakho kuyanda.Ngokuvamile, izinga lokushisa locingo lwe-tungsten lihlobene namandla ayo kagesi.Ezisetshenziswa zikagesi ezijwayelekile, intambo ye-tungsten ivamise ukusebenza phakathi kuka-2000-3000 degrees Celsius.Lapho izinga lokushisa lidlula ama-degree angu-4000, ukunwetshwa kocingo lwe-tungsten kwanda kakhulu, okungaholela ekulimaleni kocingo lwe-tungsten.

Ukunwetshwa kwentambo ye-tungsten kubangelwa ukuqina kokunyakaza kwe-molecular thermal kanye nokwanda kokudlidliza kwe-athomu ngemva kokushisisa, okwenza buthaka ukukhangana phakathi kwama-athomu futhi kuholele ekwenyukeni kwebanga le-athomu.Ngaphezu kwalokho, izinga lokunwetshwa nokuphumula kocingo lwe-tungsten nalo liyathinteka ekushintsheni kokucindezeleka.Ngaphansi kwezimo ezijwayelekile, intambo ye-tungsten ingaphansi kwezinkambu zengcindezi ngezindlela ezihlukene, okuholela ezimweni ezihlukene zokunwetshwa nokufinyela kumazinga okushisa ahlukene.

Ukushintsha kwezinga lokushisa kwentambo ye-tungsten kungabangela isenzakalo sokunweba, futhi inani lokunweba lilingana nezinga lokushisa futhi lithintwa izinguquko zengcindezi.Lapho uklama futhi ukhiqiza imishini kagesi, kuyadingeka ukulawula izinga lokushisa lokusebenza kanye nesimo sokucindezeleka socingo lwe-tungsten ukuze ugweme ukunwetshwa ngokweqile kocingo lwe-tungsten ezindaweni ezinokushisa okuphezulu kanye nomonakalo.
