From German Scheelit, named after Karl Wilhelm Scheele (1742–86), Swedish chemist.
CHE SIGNIFICA SCHEELITE IN INGLESE
scheelite
Scheelite è un minerale di tungstato di calcio con la formula chimica CaWO4. È un minerale importante di tungsteno. I cristalli ben formati sono ricercati dai collezionisti e vengono talvolta trasformati in pietre preziose quando sono opportunamente prive di difetti. Scheelite è stato sintetizzato attraverso il processo Czochralski; Il materiale prodotto può essere usato per imitare il diamante, come uno scintillatore o come mezzo di sollevamento a stato solido.
definizione di scheelite nel dizionario inglese
La definizione di scheelite nel dizionario è un minerale bianco, brunastro o verdastro, solitamente fluorescente, costituito da tungstato di calcio in forma cristallina tetragonale con un po 'di tungsteno sostituito spesso dal molibdeno: si verifica principalmente nelle rocce metamorfiche di contatto e nelle vene di quarzo, ed è un importante fonte di tungsteno e tungstato di calcio purificato. Formula: CaWO4.
