Product information "Neodymium(III) praseodymium(III) oxalate, 5:1, TREO 99.9%, rare-earth mixed oxalate, didymium"
Didymium Today, however, the term is no longer used because the rare earths have been identified and divided into individual elements.
Didymium was first discovered in 1841 by the Swedish chemist Carl Gustaf Mosander. He isolated it from cerite, a mineral that is a mixture of rare earths. However, it later turned out that Didymium itself is a mixture of the elements Praseodymium and neodymium. Didymium with its essential components Praseodymium and Neodymium finds a wide range of applications in glass technology and electronics. For example, they are used for the production of Permanent magnets, Lasers / optical fibers, Glasses (special glasses for glassblowers - yellow filters) and Ceramics (glazes) used. It is also occasionally used as a catalyst in pyrotechnics and rocket technology.

At high temperatures, the mixed oxalate decomposes into the corresponding oxides. This means that the didymium can easily be further processed in other fields of application.
