| 摘要 |
The present invention provides particulate titanium oxide and a production process thereof. The particulate titanium oxide comprises mixed crystal titanium oxide containing rutile crystal produced by a vapor phase process, wherein the titanium oxide has a property represented by the following general formula <?in-line-formulae description="In-line Formulae" end="lead"?>R>=1300xB<SUP>-0.95</SUP><?in-line-formulae description="In-line Formulae" end="tail"?> wherein R represents a rutile content (%) and B represents a BET specific surface area (m<SUP>2</SUP>/g). The titanium oxide is particulate high-rutile-content titanium oxide with very low aggregation and having a high dispersibility.
