ytterbia การใช้

ประโยคมือถือ
  • Pieces of rare earth metal which was discovered as an impurity in the mineral ytterbia.
  • In 1907, the French chemist Georges Urbain separated Marignac's ytterbia into two components : neoytterbia and lutecia.
  • All of these researchers found lutetium as an impurity in the mineral ytterbia, which was previously thought to consist entirely of ytterbium.
  • He suspected that ytterbia was a compound of a new element that he called " ytterbium " ( in total, four elements were named after the village, the others being yttrium, terbium and erbium ).
  • The Austrian chemist Carl Auer von Welsbach independently isolated these elements from ytterbia at about the same time, but he called them aldebaranium and cassiopeium; Urbain and Welsbach accused each other of publishing results based on the other party.
  • The ytterbium ( III ) ion absorbs light in the near infrared range of wavelengths, but not in visible light, so the mineral ytterbia, Yb 2 O 3, is white in color and the salts of ytterbium are also colorless.
  • In 1878, the Swiss chemist Jean Charles Galissard de Marignac separated from the rare earth " erbia " another independent component, which he called " ytterbia ", for Ytterby, the village in Sweden near where he found the new component of erbium.
  • In 1907, the new earth " lutecia " was separated from ytterbia, from which the element " lutecium " ( now lutetium ) was extracted by Georges Urbain, Carl Auer von Welsbach, and active laser media, and less often as a gamma ray source.
