. What are interstitial compounds
Why do these compounds have higher melting points than corresponding pure metals?
Best Answer
Explanation:
Interstitial compounds are those compounds of the transition metals which are formed when small atoms like H,C or N are trapped inside the interstitial vacant spaces in the crysal lattices of the metals. Some of the examples of interstitial compounds are
TiC,TiH1.73,Mn4N,Fe3H,etc.
The interstitial compounds have high melting point due to the following reasons.
∙ They are very hard.
∙ They are chemically inert, and
∙ The presence of the foreign atoms stablizes the crystal structure.
