Abstract: A method for manufacturing a foam material by using a molten slag includes: introducing the molten slag maintained at 1400° C.-1500° C. into a pool for preserving heat, and adding a viscosity modifier and/or a color modifier to the molten slag to adjust a viscosity and/or a color a product manufactured. The molten slag is discharged into a foaming pour while adding a foaming agent to the molten slag, while controlling the foam and mold at 1250° C.-1400° C. The foamed and molded slag is maintained at 800° C.-1000° C. for 20-30 minutes in a non-reducing atmosphere, and then naturally cooled to a room temperature to obtain the foam material. The produced inorganic nonmetal foam material and products thereof have such characteristics as stable color quality, abrasion resistance, pressure resistance, small thermal conductivity, small shrinkage ratio, and excellent sound absorption, adsorption and filtering performances.
