Title:
NONCRYSTALLINE COMPOSITE ALKALI METAL TITANATE COMPOSITION AND FRICTION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2009/035166
Kind Code:
A1
Abstract:
A noncrystalline composite alkali metal titanate composition which comprises
at least 60 wt.% alkali metal titanate represented by the general formula M2O
nTiO2 (wherein M is one or more alkali metal elements and n is a number
of 1 to 4) and at least 10 wt.% SiO2 and satisfies M2O/SiO2≤2.5.
It is chemically stable, has excellent resistance to moisture absorption,
and is suitable for use as a base for friction materials. If desired, the composition
can further contain an oxide of at least one member selected from the group consisting
of B, Mg, Al, P, Ca, and Zn and/or an oxide of at least one member selected from the
group consisting of V, Cr, Mn, Fe, Co, Ni, Cu, Y, Zr, Nb, and Ba.
