分散分子式：CAS号：性质：两相系统，其中一相由分得很细的粒子(通常在胶体大小范围)组成，分布于整个大物质问，粒子称分散相或称内相而大物质称作连续相或称外相。在自然条件下这种分布通常不均匀，但在控制下可以增进均匀度。方法是加入润湿剂或分散剂(界面活性剂)例如脂肪酸。不同的可能系统有：气体/固体(泡沫塑胶)；液体/气体(雾)；气体/液体(泡沫)；固体/气体(烟雾)；液体/液体(乳化)；固体/液体(漆)；及固体/固体(炭黑在橡胶中)。有些形式，例如牛乳及橡胶浆的稳定是借保护胶体的附着涂膜防止分散粒子的集结。固体在液体中的胶体分散(不严格地称溶液)可经由加入电解质中和粒子上的电荷而将其沉淀下来。较大颗粒会逐渐集结上升或下沉则视其密度而定。
