POLISHING MATERIAL, METHOD FOR PRODUCING SAME, AND POLISHING MATERIAL COMPOSITION

摘要

Taking into consideration the situation that conventional α-alumina particles for polishing have not been sufficient in terms of polishing speed and with regards to mirror surface processing, provided is an α-alumina for polishing that can be used for mirror surface processing, has low occurrence of scratches at the surface to be polished, has a particularly rapid polishing speed, and has superior polishing characteristics. The polishing material comprising α-alumina having a BET specific surface area of 0.01-20 m2/g is characterized by the α-alumina being obtained by baking an aluminum compound in the presence of a molybdenum compound.
