Kaolinite Mineral Data

Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity, making it ideal for many industrial applications. Uses During 2013, 48% of Kaolin was used in paper production, and 52% was used for ceramics, light bulbs, paint, rubber, adhesives, smoking pipes, white wash in masonry, absorbents, and in soap.

Kaolin | Al2O7Si2 - PubChem

Garnet is not a single mineral, but a group contains closely related, isomorphous minerals that form a series with each other. The Garnet members form intermediary minerals between each member, and may even intergrow within a single crystal. The Garnets vary only slightly in physical properties, and some of the members may be so similar that they are indistinguishable from one another without ...
