A homogeneous crystalline structure in which one or more types of atoms or molecules may be partly substituted for the original atoms and molecules without changing the structure is called 'solid solution'.
(Or)
A solid solution is a solid state solution of one or more solutes in a solvent. Such a mixture is considered a solution rather than a compound when the crystal structure of the solvent remains unchanged by addition of the solutes, and when the mixture remains in a single homogeneous phase.
In a solid solution the atoms occur in a definite geometrical pattern, which is usually a slightly distorted form of one of the constituent metals.
Solid solutions are conductors, but not so good as the pure metals on which they are based.
Example:
- Cu-Zn alloys (brasses)
- Ni-Cu alloys (Monel metal)
- Au-Ag alloys
- Ag-Cu alloys
- Fe-C alloys.
