Ziziphi izinto ezisetyenziselwa isinyithi seBarium?
Ukusetyenziswa okuphambili kwesinyithi se-barium njenge-arhente yokukhupha i-degassing ukususa i-trace gases kwiityhubhu ze-vacuum kunye ne-TV. Ukongeza inani elincinci le-barium kwi-alloy ekhokelayo yepleyiti yebhetri inokuphucula ukusebenza. I-Barium ingasetyenziselwa njenge-1. Iinjongo zonyango: I-Barium sulfate isetyenziswa ngokuqhelekileyo ...Funda ngokugqithisileyo -
Yintoni i-niobium kunye nokusetyenziswa kwe-niobium?
Ukusetyenziswa kwe-niobium Njengesongezo se-iron-based, i-nickel-based and zirconium-based superalloys, i-niobium inokuphucula iimpawu zabo zamandla. Kushishino lwamandla e-atom, i-niobium ifanelekile ukuba isetyenziswe njengesixhobo se-reactor kunye nemathiriyeli yokugquma yamafutha enyukliya, kunye ...Funda ngokugqithisileyo -
Iipropati, ukusetyenziswa kunye nokulungiswa kwe-yttrium oxide
