It combines directly with nitrogen, when heated in the gas, to form the nitride Mg3N2 (see Argon).
When free from nitride it is silver-white in color, and has a brilliant surface.
It blackens in the air, forming a nitride, and decomposes water.
After fusion, the melt is well washed with dilute hydrochloric acid and then with water, the nitride remaining as a white powder.
It rapidly alters on exposure to the air, probably forming a nitride.
A nitride appears to be formed when nitrogen is passed over heated iron, since the metal is rendered brittle.
nitride ni·tride (nī'trīd')
A compound containing nitrogen with another more electropositive element, such as phosphorus or a metal.
