ABRASIVE MATERIAL FOR SHOT BLASTING, AND METHOD FOR PRODUCING SAME

摘要

The abrasive material contains Fe, Si, Ca, Al, Mg and Mn and has an amorphous continuous phase, wherein the total amount of Fe, Si and Ca is 50.0% or more by mass in terms of the total content of FeO, SiO2 and CaO, Fe is contained in an amount of 6.0% to 35.0% by mass inclusive in terms of FeO content, Si is contained in an amount of 15.0% to 35.0% by mass inclusive in terms of SiO2, and Ca is contained in an amount of 10.0% to 35.0% by mass inclusive in terms of CaO content, wherein all of the amounts are those relative to the entire amount of the abrasive material.
