摘要

Provided are novel titanium oxide particles, production method thereof, and applications which do not need a conductive aid or minimize the conductive aid. Novel titanium oxide particles 1 employ a three-dimensional network structure in which multiple crystallites 2 are coupled in sequence, and a magneli phase 2a is formed on the surface of the crystallites 2. The crystallites 2 are oriented at random, coupled with each other via pinacoid or end surface, and laminated as the three-dimensional network structure. A large number of spaces 3 in nano size is present in the titanium oxide particles 1, a grain boundary of the bondinginterface is eliminated between the crystallites 2, while a large number of pores is present.
