Mixture

A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample.
Mixtures can be either homogeneous or heterogeneous.

Suspension (chemistry)

suspensionsuspensionsaqueous suspension
In chemistry, if the volume of a homogeneous suspension is divided in half, the same amount of material is suspended in both halves of the substance.
In chemistry, a suspension is a heterogeneous mixture that contains solid particles sufficiently large for sedimentation.

Solution

solutesolutessolutions
A solution is a special type of homogeneous mixture where the ratio of solute to solvent remains the same throughout the solution and the particles are not visible with the naked eye, even if homogenized with multiple sources.
In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances.

Homogeneity and heterogeneity

heterogeneoushomogeneousheterogeneity
"Homogeneous" and "heterogeneous" are not absolute terms, but are dependent on context and the size of the sample.
In chemistry, a heterogeneous mixture consists of either or both of a) multiple states of matter or b) hydrophilic and hydrophobic substances in one mixture; an example of the latter would be a mixture of water, octane, and silicone grease.

Centrifuge

In solutions, solutes will not settle out after any period of time and they can't be removed by physical methods, such as a filter or centrifuge.

Heat

Mixtures can be characterized by being separable by mechanical means e.g. heat, filtration, gravitational sorting, centrifugation etc.

During the sampling of heterogeneous mixtures of particles, the variance of the sampling error is generally non-zero.

Gy's sampling theory quantitatively defines the heterogeneity of a particle as:

Glaze (ice)

Glaze or glaze ice, also called glazed frost, is a smooth, transparent and homogeneous ice coating occurring when freezing rain or drizzle hits a surface.

Mixing (process engineering)

In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous.

Glazing agent

A glazing agent is a natural or synthetic substance that provides a waxy, homogeneous, coating to prevent water loss from a surface and provide other protection.

Freshwater environmental quality parameters

Environmental qualitynitrogenwater quality
Freshwaters are surprisingly difficult to sample because they are rarely homogeneous and their quality varies during the day and during the year.

Colloid

Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols, colloidal emulsions, colloidal foams, colloidal dispersions, or hydrosols.

Premixed flame

flame frontlaminar flame speedlaminar planar premixed speed
Since the fuel and oxidiser—the key chemical reactants of combustion—are available throughout a homogeneous stoichiometric premixed charge, the combustion process once initiated sustains itself by way of its own heat release.

Shear wave splitting

In a homogeneous material that is weakly anisotropic, the incident shear wave will split into two quasi-shear waves with approximately orthogonal polarizations that reach the receiver at approximately the same time.
