Unlike carbon nanotubes, naturally occurring halloysite nanotubes are inexpensive, readily available in quantity, environmentally benign, and safe and easy to process. Halloysite nanotubes don't clump together, making them ideal for use in electronic fabrication and other high-tech ceramic-composite applications. The potential marketplace for naturally occurring nanotubes crosses numerous industries, representing significant potential revenues. Halloysite is a high-value clay. Its fine particle size enables halloysite to be used extensively as a suspension agent in glaze preparations. The purity of the clay and the low iron and titania content result in ceramic ware with exceptional whiteness and translucency. Therefore, halloysite clay is typically used in the manufacture of porcelain, bone china and fine china. A small but increasing amount is also used for high-tech ceramic applications. Other potential applications identified include uses in filters, inkjets, and as an ingredient in special paints applied to ships that prevent barnacles from...
