magnesiumnitridi

Magnesiumnitridi, with the chemical formula Mg3N2, is an inorganic compound. It appears as a greenish-yellow powder or crystalline solid at room temperature. Magnesiumnitridi is insoluble in water, but it reacts vigorously with it, particularly when heated, to produce magnesium hydroxide and ammonia gas. This reaction is a characteristic property of many metal nitrides. The compound is formed by the direct reaction of magnesium metal with nitrogen gas at elevated temperatures, typically above 700 degrees Celsius. Alternatively, it can be synthesized by heating magnesium oxide with ammonia. Magnesiumnitridi has a high melting point and is known for its hardness and thermal stability. It is not found naturally in significant quantities. Its applications are limited but include its use as a precursor in the synthesis of other magnesium-containing compounds and in some specialized ceramic applications due to its high hardness. The compound is also a source of ammonia upon hydrolysis.
