Document Type and Number:
WIPO Patent Application WO/2019/130941
Kind Code:
A1
Abstract:
This composite titanium oxide compound is a composite titanium oxide compound wherein primary particles of an alkali metal titanate compound and primary particles of an alkaline earth metal titanate compound are joined to form secondary particles. The secondary particles have an average particle size of 1 to 80 µm. When the concentration of elements in the secondary particles is analyzed, a region where the alkaline earth metal is detected covers 50% or more of the surface area in 3% or less of the total number of secondary particles.
