Tungsten carbide is an example of

A

substitutional solid solution

B

passive solid solution

C

sandwich solid solution

D

interstitial solid solution

Text Solution

Verified by Experts

The correct Answer is:
D
Interstitial solid solutions are formed by placing atoms of one kind into voids or interstices that exist between atoms in the host lattice. Thungsten carbide `(WC)`, an extremely hard substance, is an example of interstitial solid solution.
