A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid, while others extend the definition to include substances like aerosols and gels. The … See more Hydrocolloids describe certain chemicals (mostly polysaccharides and proteins) that are colloidally dispersible in water. Thus becoming effectively "soluble" they change the rheology of water by raising the viscosity and/or … See more The following forces play an important role in the interaction of colloid particles: • Excluded volume repulsion: This refers to the impossibility of … See more There are two principal ways to prepare colloids: • Dispersion of large particles or droplets to the colloidal dimensions by milling, spraying, … See more A colloidal crystal is a highly ordered array of particles that can be formed over a very long range (typically on the order of a few millimeters to one centimeter) and that appear analogous to their atomic or molecular counterparts.
