Home Colloidal solutions

By a colloidal solution one understands a solution, in which the solved particles are present in such a small grain size that they cannot be separated by filtration. The solved particles are larger than molecules, but they are smaller than fillers in suspensions. Therefore these colloidal solutions behave partly like genuine solutions. In order to keep such colloidal solutions stable and to prevent precipitations, wetting and dispersing agents as well as other additives are added. In foundries, colloidal graphite solutions are used as die coatings.
