Hi folks - Here is the Friday Element Quiz Answer:
The Question:
This element can be machined without sparking but as a pure metal is
completely useless as it corrodes rapidly. No pure samples of this element
were produced until 1950 as it required ion-exchange chromatography
technique. This element is used in the production of the industry's best
permanent magnets. What element is being described?
Bonus question: Who developed the ion-exchange chromatography technique as
it applies to this element and what is the name of the University where
the development happened? (both names are necessary for credit)
The Answer:
The element is Dysprosium (Dy)! Dysprosium is one of the rare earth
elements that is key in the production of the best kinds of permanent
magnets - Dy and Holmium have the highest magnetic strengths of any
elements. Dy is combined with neodymium in many magnet alloys. Dy is also
found in some ceramics such as barium titanium oxide for capacitors with
high capacitance. Frank Spedding at Iowa State University developed ion
exchange chromatography to produce pure Dy in 1950. The ion exchange
technique was then applied to other rare earth element production (such as
samarium which Denny Fritz and Curt McNamara suggested as the quiz
answer). I completed my undergrad and grad studies at Iowa State
University and many of my professors worked with Dr. Spedding - so this
quiz had a personal twist!
