Interstitial compounds are a class of chemical compounds that are formed by the insertion of small atoms or molecules, typically nonmetals, into the interstices or voids between the atoms or ions of a metallic crystal lattice. These compounds are also sometimes referred to as interstitial alloys or interstitial solid solutions.
In contrast to substitutional alloys, where one element is replaced by another in the crystal lattice, interstitial compounds involve the introduction of small atoms or molecules into the spaces between the atoms or ions of the metal lattice. These interstitial atoms or molecules are typically smaller than the atoms or ions in the metal lattice and may have significantly different chemical properties.
The most common interstitial compounds involve the insertion of hydrogen or its isotopes, deuterium and tritium, into the interstitial sites of metals such as palladium, titanium, and zirconium. These compounds are known as metal hydrides and have a number of important industrial applications, including as hydrogen storage materials and as catalysts for a variety of chemical reactions.
Other examples of interstitial compounds include the insertion of carbon into the interstitial sites of iron to form cementite (Fe3C), which is an important constituent of steel, and the introduction of nitrogen into the interstitial sites of titanium to form nitrides, which are used as hard coatings in a variety of industrial applications.
In summary, interstitial compounds are a class of chemical compounds that are formed by the insertion of small atoms or molecules into the interstitial sites of a metallic crystal lattice. These compounds have a number of important industrial applications and are a key area of study in materials science and chemistry.
Answer: The compounds formed when small atoms of H, C or N get trapped inside the crystal lattice of metals.
Explanation: What are Interstitial Compounds? The compounds formed when small atoms of H, C or N get trapped inside the crystal lattice of metals are known as interstitial compounds. A number of interstitial compounds are formed by the transition metals.
