Iron (II) nitride is a chemical compound which has a chemical formula of Fe2N2. It is a solid that is soluble in nitric acid. However, it can be toxic if it is inhaled.
This compound is made by the thermal decomposition of iron (II) oxalate. The resultant compound is a black crystalline solid. Interestingly, it absorbs carbon dioxide. In addition, it also reacts with hydrogen chloride.
Iron nitride is considered a moderate explosion hazard. Usually, it is available in powder form. If it is inhaled, it can cause acute iron poisoning. Moreover, its inorganic composition makes it a health hazard.
Iron (II) nitride can be obtained by heating electrolytic iron foil in dry ammonia. The iron is converted into nitride and the mercury content is lost.
During this process, the temperature should be in the range of 600 to 700 degrees Celsius. Nevertheless, the temperature depends on the pressure. To avoid the formation of iron (III) oxide, an inert atmosphere must be used.
Iron (II) oxide is a naturally occurring compound that occurs as a byproduct of incomplete oxidation of a metal. It is a black, crystalline solid that is not soluble in water. It is widely used in a variety of applications. It is also used to produce pigments and dyes. Some of its industrial uses include heat-absorbing glass, which is used in automobiles and buildings. Besides, it is used as a catalyst for industrial operations.
Iron (II) nitride may be used to make ferrofluids. These are colloidal solutions that are used for the production of a wide variety of materials.
