Abrasive molding and abrasive disc provided with same

摘要

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/mm2, and said abrasive molding having a relative density of 20-70% and an average particle diameter of 0.001-50 mum. 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 mum 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 mum 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/mm2.
