Ⅰ. Cov Khoom Siv Raw:
1) Ntau tshaj 99.85% ntawm cov kev coj siab tshiab thiab cov hlau tsis muaj dej tsis zoo
2) K2TIF6 (Potassium Fluotitanate)
3) c (carbon hmoov)
Piv nrog al - ti - b, nws muaj ntsev tsawg dua thiab siab dua.
Thaum kev tsim khoom thiab kev siv, haus luam yeeb tsawg dua thiab hmoov av yog tsim, nrog cov ntsiab lus al2o3, thiab xim xim yeeb dawb. Yog li ntawd, kev tsim khoom thiab siv cov roj caranium yog ntau ib puag ncig ua phooj ywg, tshuaj ntxuav, nqus tau, nqus tau thiab rov ua dua.
Ⅱ. Xws li:
Tial3: Feem ntau nyob rau hauv pas nrig {{1} zoo li tus lej, discolving tus nqi yog nyob ib puag ncig 40 μm / min.
Tic: Lives ntawm ob atoms, cov qauv siv lead ua ntau dua, thiab qhov loj me yog tsawg dua 2μm.
