Title:
LITHIUM POTASSIUM TITANIUM OXIDE AND METHOD FOR PRODUCING SAME, FRICTION MODIFIER, FRICTION MATERIAL COMPOSITION, FRICTION MATERIAL, AND FRICTION MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/112698
Kind Code:
A1
Abstract:
Provided is lithium potassium titanium oxide which can increase a friction coefficient in a high-load region and can improve the stability of a friction coefficient when used in a friction material. The lithium potassium titanium oxide is represented by the compositional formula: K0.10 to 0.44Li0.27Ti1.73O3.65-3.82, in which the half width of a peak observed in a range of diffractive angles 2θ of 10.9° to 11.6° in an X-ray diffraction measurement of the lithium potassium titanium oxide is 0.20° or more.
