Neodymium is a rare earth metal which has some very interesting properties. The applications for neodymium include magnets (strongest permanent magnets known), colorant for welder’s glasses, cyrocoolers (high specific heat capacity), light filters, fertilizers, and for lasers.
Neodymium is both a soft and ductile material. It is most often alloyed with other elements, which gives it a wider range of properties. Preparation concerns include avoiding embedded abrasives by using alumina lapping films.
