Yttrium nitride is an inorganic chemical compound of yttrium from the group of nitrides .

Extraction and presentation

In principle, yttrium nitride can be synthesized from the elements. However, since compact yttrium only reacts very slowly and incompletely with nitrogen or ammonia , one is forced to use finely divided metal or high reaction temperatures. In doing so, however, there is a risk that oxygen will be dragged into the reaction product and that it will remain inhomogeneous. It is better if made of yttrium first by means of hydrogen Yttriumhydrid is formed, which is formed in relaxed form and can then be easily transferred at 800 ° C into the nitride.
