Abstract:
Provided are porous titanate compound particles capable of giving excellent fade resistance and moisture-proof properties when used in a friction material, a friction material composition, a friction material, a friction member, and a method for producing the porous titanate compound particles. Porous titanate compound particles have a cumulative pore volume of 5% or more within a pore diameter range of 0.01 to 1.0 μm, are each formed of titanate compound crystal grains bonded together, and each includes a treated layer formed on a surface thereof and made of a hydrophobic surface treatment agent.

Claim (Index 2):
The porous titanate compound particles according to  claim 1 , wherein the hydrophobic surface treatment agent is alkoxysilane represented by the following general formula (1):\n R 1 n Si(OR 2 ) 4-n \u2003\u2003(1) where in the general formula (1) n represents an arbitrary integer selected from 1 to 3; R 1  represents an alkyl group, an alkenyl group or an aryl group, each group having a substituent or being free of substituent; as for R 1  comprising a plurality of R 1  s, the plurality of R 1  s are identical to or different from each other; R 2  is an alkyl group having a substituent or free of substituent; and as for R 2  comprising a plurality of R 2 s, the plurality of R 2 s are identical to or different from each other.
