Absorption of gas occurs, but at a certain concentration the solid solution can separate into two immiscible solid solutions.
In this case the solid phase is a solid solution or a mixed crystal.
With regard to the two end portions, these represent bivariant, two-phase systems, consisting of a solid solution and gas.
If the solid phase is a solid solution, the composition will now be found different from that found previously.
In this case the alloy is called a 'solid solution' of one metal in another.
A "phosphor" is in reality an example of a solid solution and is the basis of some kinds of luminous paints.
|solid solution |
A uniform mixture of substances in solid form. Solid solutions often consist of two or more types of atoms or molecules that share a crystal lattice, as in certain metal alloys. Much of the steel used in construction, for example, is actually a solid solution of iron and carbon. The carbon atoms, which fit neatly within the iron's crystal lattice, add strength to its structure.
