Titanate having alkali metal titanate bonded thereto, process for producing the same, and resin composition containing titanate having alkali metal titanate bonded thereto

A titanate having an alkali metal titanate bonded thereto. This material, when used as a friction modifier, has excellent frictional and wearing properties and, when used as a dielectric, is excellent in mechanical properties and dielectric characteristics. Also provided are a process for producing the titanate and a resin composition containing the titanate. The titanate having an alkali metal titanate bonded thereto is characterized by comprising a titanate represented by the formula (1) and an alkaline earth metal titanate represented by the formula (2) bonded to the surface of that titanate. AxMy square Ti2-(y+z)O4 (1) (In the formula, A and M respectively are different metals each having a valence of 1 to 3; square indicates a Ti-deficient part; x is a positive real number satisfying 0
