One company has found a way to make commercial quantities of naturally occurring nanotubes that are not carbon. The halloysite nanotubes, containing the elements aluminum, silicon, hydrogen, and oxygen, are found in halloysite clay found in the soil in certain areas in the country. Halloysite clay has historically been used to make fine china and ceramics.
The company, NaturalNano, is developing methods of processing the halloysite clay into nanotubes for use in commercial applications. The halloysite nanotubes can be used in such products as additives in polymers and plastics, electronic components, cosmetics, and absorbents.
