Oxidized rare earth tungsten (W-REO)
Oxidized rare earth tungsten (WLa, WCe, WTh, WY le lisebelisoa tse ling tse sa tloaelehang tsa lefats'e) e na le matla a phahameng le ts'ebetso e khethehileng ea ho ntša metsi ho feta tungsten e hloekileng, 'me e sebelisoa haholo ho li-electrode tse fapaneng: TIG welding, welding plasma, welding plasma, plasma spray coating, ho qhibiliha ha plasma le mohloli o khanyang oa khase; e boetse e sebelisoa likarolong tsa sebopeho sa mocheso o phahameng.
Lanthanate tungsten ke motsoako oa oxidized lanthanum doped tungsten alloy. Ha lanthanum oxide e qhalakantsoeng e eketsoa, lanthanated tungsten e bonts'a ho hanyetsa mocheso o matlafalitsoeng, conductivity ea mocheso, khanyetso ea creep, le mocheso o phahameng oa recrystallization.

Potassium-doped Tungsten (Tungsten-potasiamo kapa WK)
Potassium (K) -doped W e na le li-nano-bubbles ka tatellano ea ppm e ka sitisa ho sisinyeha ha meeli ea lijo-thollo le ho arohana, ho lebisa ho matlafatsoa ka mocheso o phahameng le ho hatelloa ha recrystallization 'me e ka hlahisa lijo-thollo tse ntle ha li bapisoa le W. lijo-thollo tsena. ho hloekisoa ho boetse ho lebisa ho matlafatsoa le ho thatafala. Ho feta moo, ho lebeletsoe hore embrittlement e bakoang ke neutron-irradiation e ka hatelloa ka K-doped W ha e bapisoa le W e hloekileng hobane e na le meeli e mengata ea lijo-thollo e sebetsang e le sink bakeng sa mefokolo e entsoeng ke mahlaseli a neutron.
