Illite is the name for mica-like clay minerals, which - contrary to bentonites - do not show any swelling characteristics. Chemically (chemical data) seen they correspond to muscovite (bright mica), however they show only a grain size up to 2µm. Illite can be formed from kaolin, if potassium is added.
