any homogenous crystalline solid, consisting of more than one type of molecule or atom randomly dispersed, in which the structure is independent of its composition
A single, solid, homogenous crystalline phase containing two or more chemical species
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. Solid form of a liquid solution. As with liquids, a tendency for mutual solubility exists between any two coexisting solids (i.e., each can mix with the other); depending on the chemical similarities of the solids, mutual solubility of two substances may be 100% (as between silver and gold), or it may be near 0 (as between copper and bismuth)
a single crystalline mineral phase which may range in composition anywhere between two endmember compositions For example an Mg-Fe solid solution carbonate must contain both Mg and Fe, but the composition may range in chemistry anywhere between (but not including) magnesite and siderite
a single, solid, homogeneous crystalline phase containing two or more chemical species
a homogeneous solid that can exist over a range of component chemicals; a constituent of alloys that is formed when atoms of an element are incorporated into the crystals of a metal
