colloidal system
How are particles of colloidal size formed?
Particles of colloidal size are formed by two methods: Dispersion methods: that is, by breaking down larger particles. For example, paint pigments are produced by dispersing large particles by grinding in special mills. Condensation methods: that is, growth from smaller units, such as molecules or ions.
How can we prepare a colloidal system?
We can prepare a colloidal system by producing particles of colloidal dimensions and distributing these particles throughout a dispersion medium. Particles of colloidal size are formed by two methods: Dispersion methods: that is, by breaking down larger particles.
What is a colloidal system?
Colloid, any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye. Colloidal systems may exist as dispersions of one substance in another or as single materials. Learn more about colloids in this article.
