fergusonite การใช้

• Other minerals include samarskite and fergusonite.
• "' Fergusonite "'is a mineral comprising a complex oxide of various rare earth elements.
• Well-known minerals containing yttrium include gadolinite, xenotime, samarskite, euxenite, fergusonite, yttrotantalite, yttrotungstite, yttrofluorite ( a variety of fluorite ), thalenite, yttrialite.
• The chemical formula of fergusonite species is ( Y, REE ) NbO 4, where REE = rare-earth elements in solid solution with Y . Yttrium is usually dominant ( the species fergusonite-( Y ) ), but sometimes Ce or Nd may predominate in molar proportion ( species fergusonite-( Ce ) and fergusonite-( Nd ) ).
