A heterogeneous mixture in which relatively large solid particles are dispersed in a liquid or gas. Unlike colloids, suspended particles eventually settle under gravity. They can be separated by filtration. Blood, muddy water, and paint are examples of suspensions.
Suspensions are used in pharmaceutical formulations (e.g., antacid suspensions) where the active ingredient is insoluble. Paint and many medicines are formulations containing suspensions. Clay suspensions (drilling muds) are used in oil well drilling.
Airborne suspensions of solid particles can be inhaled and cause respiratory harm (dust hazard). Pharmaceutical suspensions must be well-mixed before use to ensure accurate dosing.
