Xa i-tungsten ishushu, ibonisa inani leempawu ezinomdla. I-Tungsten ineyona ndawo iphezulu yokunyibilika kuzo zonke iintsimbi ezisulungekileyo, ngaphezu kwe-3,400 degrees Celsius (6,192 degrees Fahrenheit). Oku kuthetha ukuba inokumelana namaqondo obushushu aphezulu kakhulu ngaphandle kokunyibilika, iyenza ibe yeyona nto ifanelekileyo kwizicelo ezifuna ukumelana nobushushu obuphezulu, njengemicu yebhalbhu yokukhanya kwe-incandescent,izinto zokufudumeza, kunye nezinye izinto ezisetyenziswa kwimizi-mveliso.

Kubushushu obuphezulu, i-tungsten iphinda ikwazi ukumelana nomhlwa, iyenze ilungele ukusetyenziswa kwindawo apho ezinye iintsimbi zinokwehla khona. Ukongeza, i-tungsten ine-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, oku kuthetha ukuba ayandi okanye ayinciphisi kakhulu xa ishushu okanye ipholile, eyenza ibe luncedo kwizicelo ezifuna ukuzinza kwe-dimensional kumaqondo aphezulu. imfezeko kwaye ibonise iipropati ezizodwa ezenza ukuba zixabiseke kakhulu kuluhlu olubanzi lwezicelo zobushushu obuphezulu.

I-Tungsten wire yinto esetyenziswa ngokuqhelekileyo kwiinkalo zezixhobo zombane, ukukhanya, njl. Intambo ye-Tungsten iyancipha kwaye iyancipha ngexesha lokutshintsha kweqondo lokushisa, elichongwa yimpawu zalo ezibonakalayo. Xa iqondo lokushisa linyuka, i-molecular thermal motion ye-tungsten wire yanda, ukukhanga kwe-interatomic kuncipha, okukhokelela ekutshintsheni okuncinci kubude bentambo ye-tungsten, oko kukuthi, into yokwandisa iyenzeka.

Ukwandiswa kocingo lwe-tungsten kuhambelana ngokuhambelana neqondo lokushisa, oko kukuthi, njengoko izinga lokushisa linyuka, ukwandiswa kwentambo ye-tungsten kwandisa. Ngokuqhelekileyo, iqondo lokushisa locingo lwe-tungsten lihambelana namandla ayo ombane. Kwizixhobo zombane jikelele, ucingo lwe-tungsten lusebenza ngokubanzi phakathi kwe-2000-3000 degrees Celsius. Xa izinga lokushisa lidlula ama-degrees angama-4000, ukwandiswa kocingo lwe-tungsten kwanda kakhulu, oku kunokukhokelela kumonakalo kwintambo ye-tungsten.

Ukwandiswa kocingo lwe-tungsten kubangelwa ukunyanzeliswa kwentshukumo ye-molecular thermal kunye nokwanda kwe-atomic vibration frequency emva kokufudumala, okwenza buthathaka umtsalane phakathi kwe-athomu kwaye ikhokelela ekwandeni komgama we-athomu. Ukongezelela, izinga lokwandiswa kunye nokuphumla kocingo lwe-tungsten nalo luchaphazeleka lutshintsho loxinzelelo. Phantsi kweemeko eziqhelekileyo, ucingo lwe-tungsten luphantsi kwemimandla yoxinzelelo kumacala ahlukeneyo, okukhokelela ekukhuliseni okuhlukeneyo kunye neemeko zokunciphisa kumaqondo okushisa ahlukeneyo.

Ukutshintsha kweqondo lokushisa kwentambo ye-tungsten kunokubangela ukwanda kwesiganeko, kwaye isixa sokwandiswa silingana nobushushu kwaye sichaphazeleka ngokutshintsha koxinzelelo. Xa uyila kunye nokuvelisa izixhobo zombane, kuyimfuneko ukulawula ubushushu bokusebenza kunye nemeko yoxinzelelo lwentambo ye-tungsten ukuphepha ukwandiswa okugqithisileyo kocingo lwe-tungsten kwiindawo eziphezulu zokushisa kunye nomonakalo.
