Definition: The most important members of the kaolin sub group of minerals are kaolinite and halloysite Kaolinite has the formula Al 2 Si 2 O 5 (OH) 4 and typically occurs in platy forms Halloysite has a similar composition except that it contains additional water molecules between the layers and most commonly has a tubular morphology.

Halloysite is non-toxic and natural - demonstrating high biocompatibility without posing any risk to the environment It is chemically identical to commonly used kaolin clay (Al 2 Si 2 O 5 (OH) 4 x nH 2 O) with one layer of water molecules existing between layers of alumina and silica Formation occurs when kaolin sheets roll into tubes due to.

The term Kaolinite describes the name of a group of closely-related clay minerals, as well as an individual member mineral of the group The members of the Kaolinite group all have the same (or similar) chemical formula, and they are Dickite, Kaolinite, Nacrite, Halloysite, and Odinite.

Halloysite is a dioctahedral 1:1 clay mineral of the kaolin group It is chemically similar to kaolinite, but the unit layers in halloysite are separated by a monolayer of water molecules; thus, halloysite has a structural formula of Al 2 (OH) 4 Si 2 O 5 n H 2 O.

Kaolinite, dickite, nacrite, and halloysite can be differentiated from chlorite by comparisons of the 358-angstrom kaolin peak with the 354-angstrom chlorite peak (Biscaye, 1965), and from chlorite and the trioctahedral members of this group by intercalation with potassium acetate (Wada, 1965).
