Yiziphi ukusetshenziswa kwe-Barium metal?
Ukusetshenziswa okuyinhloko kwensimbi ye-barium kufana ne-ejenti yokukhipha umoya ukuze kukhishwe ama-trace gases kumashubhu e-vacuum namashubhu kamabonakude. Ukwengeza inani elincane le-barium ku-alloy eholayo yepuleti lebhethri kungathuthukisa ukusebenza. I-Barium ingasetshenziswa futhi njenge-1. Izinjongo zezokwelapha: I-Barium sulfate ivame ukusetshenziswa ...Funda kabanzi -
Iyini i-niobium kanye nokusetshenziswa kwe-niobium?
Ukusetshenziswa kwe-niobium Njengesengezo se-iron-based, i-nickel-based and zirconium-based superalloys, i-niobium ingathuthukisa izakhiwo zabo zamandla. Embonini yamandla e-athomu, i-niobium ifanele ukusetshenziswa njengesakhiwo se-reactor kanye nempahla yokuhlanganisa yamafutha enuzi, kanye ...Funda kabanzi -
Izakhiwo, ukusetshenziswa kanye nokulungiswa kwe-yttrium oxide
Ukwakheka kwecrystal ye-yttrium oxide Yttrium oxide (Y2O3) iyi-oxide yomhlaba engavamile emhlophe engancibiliki emanzini ne-alkali futhi inyibilika ku-asidi. Iwuhlobo lwe-C olujwayelekile lwe-sesquioxide yomhlaba olunesakhiwo se-cubic esigxile emzimbeni. Ithebula lepharamitha yeCrystal ye-Y2O3 Crystal Structure Diagram ye-Y2O3 Engokomzimba a...Funda kabanzi -
Uhlu lwezinto eziyi-17 ezingavamile ezisetshenziswayo (ezinezithombe)
Isingathekiso esivamile siwukuthi uma uwoyela uyigazi lemboni, khona-ke umhlaba ongavamile uyivithamini yezimboni. Umhlaba ongavamile isifinyezo seqembu lezinsimbi. I-Rare Earth Elements,REE) itholakale ngokulandelana kusukela ekupheleni kwekhulu le-18. Kunezinhlobo eziyi-17 ze-REE, kufaka phakathi i-15 la...Funda kabanzi
