Abstract

Abstract

A rapidly air-cooled ladle furnace slag (RA-LFS), which is a type of steelmaking slag discharged from a steel mill, was used to synthesize CaCO₃ film. The CaCO₃ film with 35 cm² of surface area was synthesized under atmospheric conditions, and the surface morphology of the CaCO₃ films was changed by using additives (CaCl₂ and ethylene glycol). Especially, the addition of CaCl₂ changed the surface morphology of CaCO₃ film with pore and induced new material properties, such as water adsorption. The (012) face of CaCO₃ film (calcite) was rapidly decreased by the addition of CaCl₂. The major components of RA-LFS were calcium (type of CaO, 53.9wt%) and aluminum (type of Al₂O₃, 37.9wt%), and the major crystal phases of RA-LFS were C₃S, C₁₂A₇, and C₃A. The calcium extraction efficiency of RA-LFS was significantly increased after the CaCO₃ film synthesis. The material properties (hardness and elastic modulus) and the thermal characteristics of the CaCO₃ films were analyzed by nano-indentation and thermogravimetry-differential thermal analysis. The synthesized CaCO₃ films from RA-LFS and Ca(OH)₂ (reagent) showed similarities in terms of their material properties and the decomposition temperature.
