Abstract

Halloysite powder is disclosed. The halloysite powder includes a granule in which halloysite including halloysite nanotubes and titanium oxide are aggregated. The granule includes a first pore derived from a tube hole of the halloysite nanotubes, and a second pore different from the first pore. The halloysite powder may have a differential pore distribution determined from a nitrogen adsorption isotherm by BJH method exhibiting two or more pore size peaks.

Claims (2)

1 . Halloysite powder that is powder including a granule in which halloysite including halloysite nanotubes and titanium oxide are aggregated, wherein a differential pore distribution determined from a nitrogen adsorption isotherm by BJH method exhibits two or more pore size peaks in a range of 10 nm or more, and wherein a titanium oxide content in the halloysite powder is not less than 2.00 mass % and not more than 15.00 mass %.

2 . The halloysite powder according to claim 1 , wherein the granule includes a first pore derived from a tube hole of each of the halloysite nanotubes, and a second pore different from the first pore.
