Atomization is conversion of bulk liquid into a spray or mist (i.e. collection of drops), often by passing the liquid through a nozzle. Despite the name, it does not usually imply that the particles are reduced to atomic sizes, although that is the case with plasma arc waste disposal.

An atomizer is an atomization apparatus; carburetors, airbrushes, misters, and spray bottles are only a few examples of atomizers used ubiquitously. In internal combustion engines, fine-grained fuel atomization is instrumental to efficient combustion.

In some manufacturing process, fine powder is produced by spraying molten or dissolved materials through an atomizer and solidifying the droplets.
