Abstract
Coatable mixtures including erodable filler agglomerates, and abrasive articles into which they may be incorporated are presented, the agglomerates comprising a plurality of individual grains of water insoluble filler agglomerated by an agglomerating agent which includes water soluble filler and a binder. A preferred water soluble filler is Al.sub.2 (SO.sub.4).sub.3.14-18H.sub.2 O, a preferred water insoluble filler is Na.sub.3 AlF.sub.6 (cryolite), while a preferred binder is a phenolic resin. Methods of making coatable mixtures including erodable filler agglomerates are also presented.
