Abstract
Provided axe porous titanate compound particles capable of giving excellent fade resistance when used in a friction material, a resin compound and a friction material each containing the porous titanate compound particles, and a method for producing the porous titanate compound particles. Porous titanate compound particles are each formed of titanate compound crystal grains bonded together and have a cumulative pore volume of 5% or more within a pore diameter range of 0.01 to 1.0 μm.

Porous titanate compound particles each formed so that crystal grains of a titanate compound expressed by a composition formula A2Ti6O13 where A represents at least one selected from alkali metals are bonded together, the porous titanate compound particles having a cumulative pore volume of 5% or more within a pore diameter range of 0.01 to 1.0 μm.
A method for producing porous titanate compound particles each formed of titanate compound crystal grains bonded together, the porous titanate compound particles having a cumulative pore volume of 5% or more within a pore diameter range of 0.01 to 1.0 μm the method comprising the steps of:
- mechanically grinding a titanium source and an alkali metal salt to prepare a ground mixture;
- dry-granulating the ground mixture to prepare a granulated material;
- and firing the granulated material.
