kutentha kwa titaniyamu crucible kusungunula ng'anjo
Malo osungunuka a titaniyamu ndi pafupifupi 1,668 digiri Celsius (3,034 degrees Fahrenheit). Kusungunuka kwapamwamba kumeneku kumapangitsa kuti titaniyamu ikhale yoyenera kugwiritsira ntchito kutentha kwakukulu, kuphatikizapo kupanga crucibles kusungunula mu ng'anjo ndi njira zina zomwe zimaphatikizapo kutentha kwambiri.
Pa kutentha kwambiri, titaniyamu imasintha ndi machitidwe osiyanasiyana. Zina mwazofunikira za titaniyamu pa kutentha kwakukulu ndi izi:
1. Oxidation: Titaniyamu imatha kuchitapo kanthu ndi okosijeni pakatentha kwambiri kuti ipange kagawo kakang'ono ka titanium dioxide (TiO2) pamwamba pake. Wosanjikiza wa oxide uyu umapatsa chitsulo mphamvu yabwino kwambiri yolimbana ndi dzimbiri, kuteteza kuti zisapitirire makutidwe ndi okosijeni komanso kuwonongeka.
2. Kusunga mphamvu: Titaniyamu imasunga mphamvu ndi kukhulupirika kwake pa kutentha kwakukulu, zomwe zimalola kuti zikhalebe zokhazikika m'madera ovuta. Katunduyu amapangitsa titaniyamu kukhala chinthu chofunikira kwambiri pazamlengalenga, kukonza mafakitale ndi ntchito zaukadaulo zotentha kwambiri.
3. Kusintha kwa gawo: Pakutentha kwambiri, titaniyamu imatha kusintha magawo, kusintha mawonekedwe ake a kristalo ndi katundu wake. Zosinthazi zitha kugwiritsidwa ntchito kuti zigwirizane ndi zinthu zomwe zimagwiritsidwa ntchito mwapadera.
4. Reactivity: Ngakhale titaniyamu nthawi zambiri imalimbana ndi dzimbiri, imatha kuchitapo kanthu ndi mpweya ndi zinthu zina pakatentha kwambiri, zomwe zimapangitsa kupanga titaniyamu ndi ma aloyi.
Ponseponse, machitidwe a titaniyamu pakutentha kwambiri amadziwika ndi kuthekera kwake kukhalabe ndi mphamvu, kukana makutidwe ndi okosijeni, ndikusintha magawo owongolera, ndikupangitsa kuti ikhale yosunthika komanso yodalirika kuti igwiritsidwe ntchito pakatentha kwambiri.
