Ngisho ohlotsheni lwe-yttrium ion oluphezulu olusindayo olungavamile olunokuqukethwe okuphezulu kwe-terbium, i-terbium conte...Funda kabanzi -
Indlela Izakhi Zomhlaba Ezingavamile Ezenza Ubuchwepheshe Banamuhla Benzeke
Ku-opera yasemkhathini kaFrank Herbert ethi “Dunes”, into yemvelo eyigugu ebizwa ngokuthi “ingxube yezinongo” inika abantu ikhono lokuzulazula endaweni yonke ukuze bathole impucuko ephakathi kwezinkanyezi. Empilweni yangempela Emhlabeni, iqembu lezinsimbi zemvelo ezibizwa ngokuthi i-rare earth elem...Funda kabanzi -
I-Magic Rare Earth Element: I-Cerium
UCerium 'umfowethu omkhulu' ongangatshazwa emndenini omkhulu wezinto ezingavamile zomhlaba. Okokuqala, inala yonke yomhlaba eyivelakancane kuqweqwe ngu-238ppm, kanti i-cerium iku-68ppm, ibalwa ku-28% wengqikithi yokwakheka komhlaba eyivelakancane futhi ibekwe kuqala; Okwesibili, i-cerium iyi-ea yesibili engavamile...Funda kabanzi -
Magical Rare Earth Elements Scandium
I-Scandium, enophawu lwe-elementi u-Sc kanye nenombolo ye-Atomic engu-21, incibilika kalula emanzini, ingakwazi ukusebenzisana namanzi ashisayo, futhi iba mnyama kalula emoyeni. I-valence yayo eyinhloko ingu+3. Ivamise ukuxutshwa ne-gadolinium, i-erbium, nezinye izakhi, ngesivuno esiphansi nokuqukethwe cishe okungu-0.0005% ku-cr...Funda kabanzi -
Isici somhlaba esingavamile somlingo i-europium
I-Europium, uphawu yi-Eu, kanti inombolo ye-Atomic ingu-63. Njengelungu elivamile le-Lanthanide, i-europium ivamise ukuba ne-+3 valence, kodwa i-oxygen+2 valence nayo ivamile. Kukhona izinhlanganisela ezimbalwa ze-europium ezinesimo se-valence esingu+2. Uma kuqhathaniswa nezinye izinsimbi ezisindayo, i-europium ayinayo i-biologica ebalulekile...Funda kabanzi -
