Abstract:
1. A method for making a refractory material comprising the steps of: providing aluminum residues of aluminum recycling; providing carboxylmethyl cellulose adhesive solution; mixing the aluminum residues with the adhesive solution so that the adhesive solution takes up 5 wt % to 10 wt % of the mixture; granulating the mixture into grains; filling the grains in a mold; pressing the grains with a uni-axial compressive force in the mold into a green body; moving the green body from the mold; and calcinating the green body at 1100° C. to 1400° C. in a furnace, thus sintering the green body into a refractory material, wherein the resulting refractory material has a composition in weight percent of 63.52 to 80.8% Al
