    摘要: A method of producing an abrasive roll comprises the steps of forming a mixture of substances such as abrasive grains, a bond, a temporary caking agent and a pore forming agent, molding the mixture into a body having a predetermined shape, and drying and then burning the body. The pore forming agent is constituted from a rice hull powder sieved to have a predetermined particle size, thereby enabling to produce an abrasive roll of high porosity which has pores having substantially ball-like shape and substantially uniform size and includes a bond having portions of high SiO.sub.2 concentration each adjacent to and surrounding one of the pores.
