Abstract

The present invention provides artificial sand comprising, for use as a material of binder-containing foundry sand, as a main component, synthetic mullite and/or synthetic corundum containing 40 to 90% by weight of alumina and 60 to 10% by weight of silica; having a particle size distribution of 30 to 1180 ?m; having a surface area per unit volume (cm2/cm3) of 6 x 104/d to 1.8 x 106/d (wherein d is an average particle size (?m) of the spherical substance); and having a calcium ion elution in a 0.05 M HCl aqueous solution of 60 mg/L or less.
