Izakhi zokushisisa ezenziwe nge-tungsten zisetshenziswa ezinhlelweni zokushisa eziphakeme ezahlukahlukene ngenxa yezakhiwo ezihlukile ze-tungsten, njengendawo yayo yokuncibilika ephezulu, amandla amahle kakhulu emazingeni okushisa aphezulu, nomfutho womoya ophansi. Nazi ezinye izinhlobo ezijwayelekile zezinto zokushisisa ezisebenzisa i-tungsten:

1. I-Tungsten Wire Heating Elements: Intambo ye-Tungsten ivame ukusetshenziswa njengento yokushisisa ezinhlelweni ezifana nezibani ze-incandescent, lapho isebenza khona njengomcu oshisa futhi ikhiqize ukukhanya lapho ugesi udlula kuwo. Izinto zokushisisa izintambo ze-Tungsten nazo zisetshenziswa eziko ezimbonini, kuhhavini, nasezinhlelweni zokufudumeza ezidinga ukusebenza kwezinga lokushisa eliphezulu.

2. I-Tungsten Ribbon Heating Elements: Iribhoni ye-Tungsten, ewuhlobo oluyisicaba futhi olubanzi lwentambo ye-tungsten, isetshenziswa ezintweni zokushisisa izinhlelo zokusebenza ezidinga indawo enkulu yokukhiqiza ukushisa. Izakhi zokushisa iribhoni ye-Tungsten zisetshenziswa ezinqubweni zokushisisa ezihlukene zezimboni, okuhlanganisa nokwelashwa kokushisa, ukufakwa kwe-annealing, nokuncibilika kwensimbi.

3. I-Tungsten Foil Heating Elements: Ucwecwe lwe-Tungsten, oluwuhlobo oluncane noluguquguqukayo lwe-tungsten, lusetshenziswa ezintweni zokushisisa ezikhethekile ezisetshenziswayo ezidinga ukushisisa okunembile nokufana. Izinto zokushisa ze-Tungsten foil zisetshenziswa ezimbonini ezifana nokukhiqiza i-semiconductor, i-aerospace, nokuvikela.

4. I-Tungsten Disilicide (WSi2) I-Heating Elements: Izakhi zokushisa ze-Tungsten disilicide zenziwe ngenhlanganisela ye-tungsten ne-silicon, enikeza ukumelana nokushisa okuphezulu kanye nokumelana okuhle kakhulu kwe-oxidation. Lezi zinto zokushisisa zisetshenziswa ezithandweni ezinokushisa okuphezulu, iziko, nezinye izinhlelo zokusebenza zokushisa ezimbonini.

Sekukonke, izinto zokushisisa ezenziwe nge-tungsten zibaluleke kakhulu ngenxa yekhono lazo lokumelana nezinga lokushisa elidlulele, zinikeze ukukhiqizwa kokushisa okuphumelelayo, nokugcina ubuqotho besakhiwo ekufuneni izindawo ezinezinga lokushisa eliphezulu. Lezi zakhi zithola ukusetshenziswa ebangeni elibanzi lezinqubo zokushisisa zezimboni, ezohwebo, nezesayensi.

I-Tungsten yaziwa ngokumelana kwayo okukhethekile nokusabela ngezinto eziningi emazingeni okushisa ajwayelekile. Leli zinga eliphakeme lokungangeni kwamakhemikhali ngenxa yezibopho zalo eziqinile ze-athomu kanye nokwakheka kongqimba lwe-oxide oluvikelayo ebusweni balo. Kodwa-ke, i-tungsten ingasabela ngezinto ezithile ngaphansi kwezimo ezithile:

1. Umoya-mpilo: I-Tungsten ingasabela komoyampilo emazingeni okushisa aphezulu ukuze yakhe ama-tungsten oxides. Lokhu kusabela kwenzeka emazingeni okushisa aphakeme, ngokuvamile angaphezu kuka-700°C, lapho i-tungsten ingakhipha i-oxidize yakhe ama-oxide afana ne-tungsten trioxide (WO3) ne-tungsten dioxide (WO2).

2. Ama-Halogen: I-Tungsten ingasabela ngama-halogen afana ne-fluorine, i-chlorine, i-bromine, ne-iodine emazingeni okushisa aphezulu ukuze yakhe i-tungsten halide. Lokhu kusabela ngokuvamile kwenzeka ngaphansi kwezimo ezimbi kakhulu futhi akuvamile ezisetshenziswa zansuku zonke.

3. Ikhabhoni: I-Tungsten ingasabela ngekhabhoni emazingeni okushisa aphezulu kakhulu ukuze yakhe i-tungsten carbide (WC), into eqinile futhi engagugi. Lokhu kusabela kuvame ukusetshenziswa ekukhiqizeni i-tungsten carbide yamathuluzi okusika nezinye izinhlelo zokusebenza zezimboni.

Ngokuvamile, ukusebenza kabusha kwe-tungsten enezici eziningi kuncane ngaphansi kwezimo ezivamile, okuyenza imelane kakhulu nokugqwala nokuhlaselwa ngamakhemikhali. Lesi sakhiwo senza i-tungsten ibe yigugu ezinhlobonhlobo zezinhlelo zokusebenza lapho ukungabi namakhemikhali kwamakhemikhali nokuzinza kwezinga lokushisa eliphezulu kubalulekile.
