Preparation of Nitrides
Nitrides are formed by directly reacting a metal with a nitrogen source, such as ammonia gas, or by reacting a metal with a nitrogen compound, such as nitric acid. During these reactions, the metal reacts with nitrogen, forming nitrides. Thermal decomposition of metal amides and reduction of metal halides or oxides in the presence of nitrogen gas are other routes to the production of versatile nitride compounds with a wide range of uses. Some of the examples of preparation of nitride is mentioned below:
Direct Reaction of Elements
Reacting elements directly is one simple technique. Using calcium nitride (Ca3N2) as an illustration:
3Ca + N2→Ca3N2
Heat Decomposition of Metal Amide
The second technique is heating a metal amide to release ammonia, such as barium amide:
3Ba(NH2)2 →Ba3N2 + 4NH3
This procedure shows an alternative route to nitride creation by releasing ammonia.
Reduction of Metal Halide or Oxide
Reducing a metal oxide or halide in the presence of nitrogen gas is an additional method. The synthesis of aluminium nitride (AlN) goes like this:
Al2O3 + 3C + N2→2AlN + 3CO
Nitride
Nitrides are a class of chemical compounds formed when nitrogen combines with less electronegativity components such as silicon or boron. It appears in nature in a variety of forms. There are three different kinds of nitrides: transition metal, covalent, and ionic. They are useful in a variety of applications and have distinct features. These nitride compounds when broken into two ions form a cation and an anion. The anion formed is called Nitride Ion.
In this article, we will learn in detail about what are nitrides, nitride ions, their formula, valency, properties, types, and uses.
