Europium (II) telluride is an inorganic chemical compound of europium from the group of tellurides .
Extraction and presentation
Europium (II) telluride can be obtained by reacting europium with tellurium at 500–1000 ° C.
The connection can also be made from europium (II) hydride and tellurium in a hydrogen stream at 600–850 ° C
or from finely divided europium (II) oxide with an excess of tellurium at 600-900 ° C or from europium (II) oxalate and tellurium.
properties
Europium (II) telluride is a black antiferromagnetic solid with a cubic crystal structure of the sodium chloride type.
