A finely divided, solid material, which when dispersed in a liquid medium, scatters a light beam and does not settle by gravity; such particles are usually less than 2 microns in diameter. Some drilli [..]

A colloid is a heterogeneous mixture composed of tiny particles suspended in another material. The particles are larger than molecules but less than 1 µm in diameter. Particles this small do not settl [..]

1847, from French colloide (1845), from Greek kolla "glue" + -oeides "form" (see -oid).

suspension in which particles of one substance are dispersed (suspended) in another substance.

A proteinaceous product of thyroid epithelial cells composed mostly of thyroglobulin.

Nanoscale or microscale particles suspended in another medium; colloids include gels, aerosols, and emulsions.

(koll-oid). Composed of microscopic-sized particles, that by reason of their great surface area, hold water and mineral elements with very great force.

A two-phase system in which particles of one phase are suspended in the second phase. colonial hypothesis

A suspension of large molecules or aggregates of smaller molecules from 1nm to 100nm in size.

(n) - a particle with a size of less than 0.00024 mm

A substance that contains components in different phases (e.g., minute solid particles within a liquid).

A type of solution in which the particles are not dissolved but are dispersed throughout the solvent or medium and held in suspension. Compatibility

(n) a mixture with properties between those of a solution and fine suspension

Particle, which may be a molecular aggregate, with a diameter of 0.1 to 0.001µm; clay and soil organic matter are often called soil colloids because they have particle sizes that are within, or approa [..]

Heterogeneous mixture of tiny particles dispersed evenly throughout a solid, liquid, or gas (Lesson 13)

As a size term refers to particles smaller than 0.00024 mm, smaller than CLAY size.

a finely divided organic substance which tends to inhibit the formation of dense scale and results in the deposition of sludge, or causes it to remain in suspension, so that it may be blown from the boiler.

insoluble particles (larger than single molecules) in a stable suspension.

A fluid substance where minute particles of one substance are dispersed, without settling, in another.

Two-phase systems in which one is uniformly dispersed in another as particles small enough so they cannot be filtered or will not settle out. The dispersing or continuous phase or medium envelops the [..]

A suspension of metallic Gold particles.

A suspension of radioactive Gold particles emitting negative Beta Particles and gamma irradiation. It was formerly used for liver scans and irradiation treatment of some metastatic malignancies.

A gamma-emitting Radionuclide Imaging agent used for the Diagnosis of Diseases in many Tissues, particularly in the gastrointestinal system, liver, and spleen.

A gamma-emitting Radionuclide Imaging agent used for the Diagnosis of Diseases in many Tissues, particularly in cardiovascular and cerebral circulation.

Material composed of ultramicroscopic particles of a solid, liquid, or gas dispersed in a different medium which can be a solid, liquid, or gas.

If the size of a particle is of the order 10 nm to 1 micron (10-8 to 10-6 metres), then a mixture of these particles with a continuous phase (e. g., tiny particles of dust in air or polymer in water) will have properties that are intermediate between those of a true solution and a mixture of largish particles in a substance. Three key things to rem [..]

A state of subdivision of matter characterized by a particle size intermediate between molecular dispersion (true solution) and a size just about visible with an ordinary microscope.

Very fine divided solid particles which will not settle out of a solution; intermediate between a true dissolved particle and a suspended solid which will settle out of solution.

a suspension of finely divided particles in a gas or liquid which do not settle and are not easily filtered. A lubricating grease is a colloidal system, in which metallic soaps or other thickening agents are dispersed in, and give structure to, the liquid lubricant.

A phase so highly dispersed that surface forces are an important factor in determining its properties.
