Abstract
An abrasive molding comprising at least 90% by weight, based on the abrasive molding, of an inorganic material having a stock hardness of 50-400 kg/mm , and said abrasive molding having a relative density of 20-70% and an average particle diameter of 0.001-50 &mgr;m. The abrasive molding preferably has pores having a pore size distribution such that the integrated pore volume of pores having a diameter of 0.01-1 &mgr;m is at least 20% of the integrated total pore volume of the entire pores, and the integrated pore volume of pores having a diameter of 1-360 &mgr;m is in the range of 10% to 70% of the integrated total pore volume of the entire pores. The abrasive molding is suitable for polishing a material having a Vickers hardness not larger than 300 kg/mm .
