Colloid: Short synonym for colloidal system. Colloidal: State of subdivision such that the molecules or polymolecular particles dispersed in a medium have at least one dimension between approximately 1 nm and 1 μm, or that in a system discontinuities are found at distances of that order.
“Colloidal” Definition. Colloidal refers to items of a small size that are floating in a medium of one of three substances: a solid, a liquid, or a gas. Colloidal particles can be suspended in a substance just like their own make-up or a different substance with the exception of gases. Gas particles will not suspend in another gas.
Colloidal particle. In Materials science and Colloidal chemistry, the term colloidal particle is about a small amount of matter having size typical for colloids and with a clear phase boundary. The dispersed-phase particles have a diameter between approximately 1 and 1000 nanometers. Colloids are heterogeneous in nature.

Colloid definition, a substance made up of a system of particles with linear dimensions in the range of about 10−7 to 5 × 10−5 cm dispersed in a continuous gaseous, liquid, or solid medium whose properties depend on the large specific surface area. The particles can be large molecules like proteins, or solid, liquid, or gaseous aggregates and they remain dispersed indefinitely.
Colloidal solutions are the type of mixture, where the solute (tiny particles or colloids) is uniformly distributed in the solvent (liquid phase). The suspension is the mixture, where the solute does not get dissolved, rather get suspended in the liquid and float freely in the medium. ... Definition of Colloidal Solution. The heterogeneous ...
