Hi folks - Here is the Friday Element Quiz Answer: The Question: This element has an isotope with a half life of 2 days. The element was approved for radiopharmaceutical use in the US in 1997. Ores containing this element are found in China, Brazil, USA and Sri Lanka. This element plays no biological role in the human body although the average amount believed to be in the human body is around 50 micrograms. This element is still used today in some microwave applications because it retains a specific characteristic above 700C. What element is being described? The Answer: The element is Samarium (Sm)! Samarium was a key element in the introduction of ferromagnetic Rare Earth magnets in the 1970s. SmCo5 is an intermetallic compound which outperforms Fe and Al-Ni-Co magnets but is significantly more costly. In the 1980s, the Nd2Fe14B intermetallic compound was found to outperform the SmCo5 IMC and was much less expensive. The NdFeB permanent magnets are now the industry's material of choice with sales exceeding $2 billion per year. Drew Meyer, Benchmark Electronic, is the quiz winner and Clumpy/Kloumpios will fire up the John Deere tractors and proceed to his facility asap. Just a information note, we have been quizzed on only 37 of the 118 elements in the Periodic table. Looks like Clumpy and Kloumpios are going to stay busy. So far Clumpy and Kloumpios have: Week 1 Lamar Young, SCS Coatings - accomplished nothing (drank lots of coffee) Week 2 Bev Christian, RIM - conducted REACH material testing Week 3 Drew Meyer, Benchmark Electronics Inc. - Solderability testing and mowed the lawn Week 4 Ian Fox, Goodrich - had an epic journey of travel Week 4 Gary Ferrari, Garrick Global - unknown Week 5 Fredrick Miller, Astrolab - unknown Week 6 David Nelson, Raytheon - Were tackling dummys for Dallas Cowboys Week 7 Graham Collins, L3 Communications - Cleaned gutters and painted window trim Week 8 Bill Noel, ITT Geospatial Systems Division - unknown Week 9 Steve Gregory of RD Circuits - unknown Week 10 David Bealer of Watchfire Signs - descaled the in-line wash machine!
