What are the properties of interstitial compound?
Answers
Answer:
Following are the significant physical and chemical properties of the interstitial compounds: These compounds have very high melting points, higher than that of the parent transition metals. These compounds are very hard. The hardness of some borides is comparable to that of a diamond.
Answer:
1) The chemical properties of the interstitial compounds are the same as that of parent transition metals.
2) They are hard and show the metallic properties like electrical and thermal conductivity, lustre, etc.
3) Since metal-non-metal bonds in the interstitial compounds are stronger than metal-metal bonds in pure metals, the compounds have very high melting points, higher than the pure metals
4)They have lower densities than the parent metal.
5) The interstitial compounds containing hydrogen (i.e., hydrides of metals) are powerful reducing agents.
6) The compounds containing carbon, hence behaving as carbides, are chemically inert and extremely hard like diamond.
7) In these compounds, malleability and ductility are changed. For example steel and cast iron.
