Abstract
An abrasive member comprises a substrate and an abrasive layer, which is overlaid upon the substrate and is constituted of a binder and abrasive grains dispersed therein. The abrasive grains contain aluminum oxide grains, which have the characteristics such that the sodium content, as calculated in terms of NaO, in the abrasive grains may be at most 0.1% by weight, and such that the grain diameter of .alpha.-crystal grains may be at most 5 .mu.m. The abrasive member is capable of abrading a material to be abraded such that scratches, corrosion, or the like, may not occur with the abraded material, and the abraded material having good quality may be obtained.
