(physics) 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.

(physics) One of the three fundamental structural phases of matter in which the cohesive force of matter is strong enough to keep the molecules or atoms in the given positions, restraining the thermal mobility.

(geometry) Any of a class of convex polyhedra that have regular faces but are not uniform (that is, not Platonic solids, Archimedean solids, prisms, or antiprisms).

(chemistry) A type of colloid, of the form of one solid dispersed in another continuous solid.

(geometry) Any of a class of convex semiregular polyhedra, composed of two or more types of regular polygon meeting in identical vertices.

(physics) Having or relating to the physical properties of solid materials, especially electromagnetic, thermodynamic or structural properties of crystalline solids.

(quantum mechanics) Any of a class of solids (such as that of helium) whose atoms or molecules undergo large zero-point motion even in the quantum ground state (at absolute zero).

(chemistry) A type of colloid, of the form of a solid dispersed in a liquid.

(geometry) The solid body generated by the intersection of two or three cylinders of equal radius at right angles.

Drawn out from a heated solid bar, as by a process of spiral rolling which first hollows the bar and then expands the cavity by forcing the bar over a pointed mandrel fixed in front of the rolls; said of a weldless tube.
