An inorganic pigment which is treated with at least one non-reactive polysiloxane of the general Formula I

##STR00001##

In general Formula I, R.sup.1 to R.sup.8 are the same or different and are selected from C.sub.mH.sub.2m+1, wherein m is ≤10, and fluorinated derivatives thereof wherein at least one hydrogen atom is replaced by fluorine, C.sub.6H.sub.5, and (EO).sub.x(PO).sub.y and copolymers thereof, wherein EO is an oxyethylene unit, PO is an oxypropylene unit, x and y are the same or different, and x+y is in the range of 1 to 50. The at least one non-reactive polysiloxane has a viscosity in the range of 50-3000 mm.sup.2×s.sup.−1 at 25° C. The inorganic pigment treated with the at least one non-reactive polysiloxane of general Formula I has a residual moisture content of less than 1 wt-%.

The invention provides a chemical-mechanical polishing composition containing aluminate-modified silica particles, a polyacrylamide, a heterocyclic film-forming agent, and water. The invention also provides a method of chemically-mechanically polishing a substrate, especially a nickel-phosphorous substrate, by contacting a substrate with a polishing pad and the chemical-mechanical polishing composition, moving the polishing pad and the polishing composition relative to the substrate, and abrading at least a portion of the substrate to polish the substrate.
