    • The artificial stone is produced by a composition containing 41 wt.% a slag(Si deoxidation steel) that is generated from during the process of Si deoxidation steel comprising 45.9-47.8 wt.% CaO, 5.0-5.3 wt.% MgO, 7.0-7.4 wt.% Al2O3, 35.3-36.8 wt.% SiO2, 1.4-1.5 wt.% MnO, 0.4-0.5 wt.% FeO and 0.4-0.5 wt.% CaF2; 26 wt.% a feldspar comprising 0.1-0.2 wt.% CaO, 0.1-0.2 wt.% MgO, 2.9-3.1 wt.% Na2O, 8.6-9.0 wt.% K2O and 66.1-68.9 wt.% SiO2; 23 wt.% a fluorite having a purity degree of 80 % or more; and 10 wt.% a silica having a purity degree of 95 % or more. The artificial stone is produced by mixing, dissolving, coagulating the raw material composition by the conventional method, and then heat treating followed by crystallizing it.
