FAQ
Q1: Nws puas tuaj yeem siv nrog hydrofluoric acid (HF)?
A: Tsis yog, quartz reacts nrog HF. Siv Teflon lossis platinum crucibles hloov.
Q2: Puas muaj kev cai loj?
A: Yog lawm, peb muab qhov ntev ntev, phab ntsa tuab, thiab cov duab.
Q3: Lub sijhawm ua haujlwm rau kev txiav txim ntau yog dab tsi?
A: Feem ntau tsis pub dhau 7 hnub, nyob ntawm seb muaj pes tsawg thiab kev hloov kho.
