A 10g sample of rare earth Europium metal in the form of several pieces of extremely high purity distilled dendritic metal. Purity is greater than 99.99%. The metal will come vacuum sealed with a coating of oil. Eu metal is not often found in such high purity. These pieces do show signs of oxidation but also have an iridescent crystalline surface texture which can be seen in the photos. Size and shape of the pieces will vary from the ones pictured, but you will receive 10g total. Europium is one of the rarer rare earths and is very reactive, shiny samples are very hard to find. This is an excellent price!
