ABSTRACT:
Friction material adapted for use, for example, as a brake lining is disclosed characterized in that the material contains in particulate form a crystalline mineral friction modifier of an isomorphous substitutional solid solution consisting essentially of atoms of metals and oxygen arranged as a mixed crystal in a normal spinel crystal lattice structure. There are at least three different metal atoms present in the crystal lattice, the total number of metal atoms having a total valence charge sufficient to maintain electrical neutrality. The friction material may be conventionally supported as by a shoe or disc.
