Question
What are interstitial compounds? Give their properties.
✓
Answer
An interstitial compound or alloy is a compound that is formed when small atoms like hydrogen, boron, carbon or nitrogen are trapped in the interstitial holes in a metal lattice. They are usually non-stoichiometric compounds, e.g., $TiC , ZrH _{1.92}, Mn _4 N$.
1. They are hlard and show electrical and thermal conductivity.
2. They have high melting points.
3. Transition metal hydrides are used as powerful reducing agents.
4. Metallic carbides are chemically inert.
