Ntxiv rau kev cuam tshuam nrog cov hlau alkali molten, nws tsis raug xeb los ntawm ib yam khoom, txawm tias nws tau rhaub hauv hydrofluoric acid, aqua regia lossis fuming sulfuric acid, sodium hydroxide, nws yuav tsis hloov pauv.
2. Tsis tshua muaj kev kub ntxhov, zoo mechanical toughness ntawm qhov kub qis, txawm tias qhov kub poob rau -196 ℃ yam tsis muaj embrittlement, nws tuaj yeem tswj tau 5% elongation.
3. Kev tiv thaiv xeb, inert rau feem ntau cov tshuaj lom neeg thiab cov kuab tshuaj, tiv taus cov kua qaub thiab alkalis muaj zog, dej thiab ntau yam kuab tshuaj organic, thiab tuaj yeem tiv thaiv cov khoom los ntawm txhua yam kev xeb tshuaj.
4. Tiv thaiv kev laus, nyob rau hauv lub nra hnyav, nws muaj ob qhov zoo ntawm kev hnav tsis kam thiab tsis lo. Nws muaj lub neej laus zoo tshaj plaws hauv cov yas.
5. Muaj lubrication siab, uas yog qhov coefficient sib txhuam qis tshaj plaws ntawm cov khoom khov. Qhov coefficient sib txhuam hloov pauv thaum lub nra hnyav swb, tab sis tus nqi tsuas yog nyob nruab nrab ntawm 0.05-0.15.
6. Tsis lo, uas yog qhov uas muaj qhov nruj me tshaj plaws ntawm cov khoom khov, thiab tsis lo rau ib yam khoom twg. Yuav luag txhua yam khoom yuav tsis lo rau nws. Cov zaj duab xis nyias heev kuj qhia tau tias nws tsis lo.
7. Nws yog dawb, tsis muaj ntxhiab, tsis muaj saj, tsis muaj tshuaj lom, thiab tsis muaj zog. Ua ib txoj hlab ntsha thiab lub cev cuav uas cog rau hauv lub cev ntev, nws tsis muaj kev phiv tshuaj.
8. Lub cev nyhav sib dua thiab muaj zog yoog tau. Nws tuaj yeem txo qhov siv zog ntawm tus neeg teb xov tooj.
9. Cov txiaj ntsig zoo ntawm cov khoom no, yog li ntawd lub neej ua haujlwm ntau dua li ntau hom dej uas twb muaj lawm, siv ntev tsis tas yuav hloov, txo cov nqi siv, txhim kho kev siv zoo, kev lag luam thiab kev siv tau zoo
