Izixhobo zokucoca zisisixhobo esiyimfuneko kushishino lwanamhlanje. Iyakwazi ukuphumeza iinkqubo eziyinkimbinkimbi ezingenakuphathwa ngezinye izixhobo zokunyanga ukushisa, oko kukuthi i-vacuum quenching kunye ne-temering, i-vacuum annealing, isisombululo esiqinileyo se-vacuum kunye nexesha, i-vacuum sintering, i-vacuum yokucoca ukushisa kweekhemikhali kunye neenkqubo zokugubungela. Ubushushu bayo beziko linokufikelela kwi-3000 ℃, kwaye i-tungsten kunye ne-molybdenum zinokumelana nobushushu obuphezulu kunye ne-coefficient yokwandisa i-thermal ephantsi, ke zihlala zisetyenziswa njengezinye izincedisi eziko.
Ngokubanzi, xa ubushushu beziko lomlilo bungaphezulu kwe-1100 degrees Celsius, i-molybdenum okanye i-tungsten iya kuthathwa njengekhuselo lobushushu (kubandakanya ii-baffles ezisecaleni kunye nezikrini ezingaphezulu nezisezantsi zokugquma): njengeendawo zokugquma ubushushu eziko, indima ephambili ye-molybdenum. isikrini se-tungsten reflector kunye namaqweqwe aphezulu nangaphantsi Ipleyiti kukuthintela kunye nokubuyisela ubushushu kwiziko. I-tungsten kunye ne-molybdenum ipleyiti yokugquma ubushushu ngokuqhelekileyo yenziwe nge-riveting, enokuthi ifakwe okanye igqitywe. Iipleyiti ezigutyungelweyo, imivalo yegridi emise u-U okanye imithombo yocingo ye-molybdenum kunye ne-spacers ingasetyenziswa phakathi kwezikrini zomaleko ngamnye, kwaye zilungiswe nge-molybdenum wire okanye i-tungsten wire clips kunye nezikrufu.
