Stainless steel plant(SSP)dust is a hazardous by-product of the stainless steelmaking industry.It contains large amounts of Fe,Ni and Cr,and can be potentially used as inorganic black pigment in the ceramic tile industry.In this paper,the physical and leaching properties of ceramic tiles with black pigment using stainless steel plant dust as a raw material were investigated by considering the process parameter of sintering temperature,sintering time,addition ratio of pigment,mineralizer addition and compress strength of sample preparation.The results show that the good physical properties of ceramic tiles can be obtained with 8%pigments addition and sample preparation pressure of 25 MPa sintering at 1200℃ for 30min.The controlling leaching mechanisms of Cr and Pb from the ceramic tiles are initial surface wash-off,while the leaching of Cd,Ni and Zn from the product are controlled by matrix diffusion.
