What is Interstitial?
In chemistry and materials science, interstitial refers to atoms, ions, or molecules that occupy the spaces (interstices) between the atoms in a crystal lattice. Interstitial sites are the small cavities between atoms in a crystal structure. Interstitial compounds are formed when small atoms (H, C, N, B) fit into these spaces in metal lattices, often dramatically altering the metal's properties.

Steel manufacturing (carbon in iron lattice creates steel — harder than pure iron). Surface hardening (nitriding, carburizing). Hydrogen storage in palladium (Pd absorbs 900× its volume H₂). Tungsten carbide (WC) cutting tools. Metal hydrides for hydrogen storage. Understanding corrosion mechanisms.
Interstitial carbon (steel) not hazardous. Interstitial hydrogen in metals can cause hydrogen embrittlement and cracking. Metal hydrides: pyrophoric risk. Interstitial nitrogen compounds: metal nitrides may be reactive. Specific compound safety varies widely.
