Document Type and Number:
WIPO Patent Application WO/2019/176166
Kind Code:
A1
Abstract:
An alkali metal titanate comprising an alkali metal titanate phase and a composite oxide containing Al, Si and Na, the alkali metal titanate being characterized in that the percentage of the ratio of the number of moles of Na to the total number of moles of Na and an alkali metal X that is different from Na, i.e., ((Na/(Na+X))×100), is 50 to 100 mol% and the percentage of the ratio of the total content of Si and Al to the content of Ti, i.e., (((Si+Al)/Ti)×100), is 0.3 to 10% by mass. According to the present invention, an alkali metal titanate can be provided, in which the content of a compound having a shorter diameter d of 3 μm or less and the longer diameter L of 5 μm or more and also having an aspect ratio (L/d) of 3 or more is small.
