Novel sintered ceramic materials incorporated with EAF carbon steel slag

Ironmaking and Steelmaking Slags as Sustainable Adsorbents for Industrial Effluents and Wastewater Treatment: A Critical Review of Properties, Performance, Challenges and Opportunities

“…Thermal treatment is also one of the proven methods for the inertisation treatment of inorganic hazardous wastes. Thermal vitrification involves the high-temperature transformation of solid wastes into environmentally stable waste forms, such as glass and ceramics, via sintering, vitrification and/or vitrification-controlled crystallisation [201,204,205,[209][210][211][221][222][223]. Thermal vitrification, in particular, converts inorganic wastes into stable and homogenous glassy phases with and without glass precursors and modifiers [204,[209][210][211].…”

“…To date, extensive studies have demonstrated that glass and glass ceramic technologies can convert silicate-based inorganic wastes to functional materials with substantial market opportunities, while at the same time, converting hazardous wastes into chemically inert glassy matrices [205,210,[221][222][223]. In particular, several studies have demonstrated the synthesis of glass ceramics from admixtures of slags and other inorganic wastes.…”

“…Karayannis et al [221] synthesised novel sintered clay-based ceramic materials incorporating EAF carbon steelmaking slag. Sintering the extruded admixtures containing 6 mass % EAF slag around 1100 • C increased the phase-transformation-induced densification, thereby improving the mechanical performance of the ceramic products.…”

Mining and metallurgical wastes: a review of recycling and re-use practices

“…Application of choline chloride and urea ionic liquids in the selective dissolution Abbott et al, 2006Abbott et al, , 2009 Ponsot and Bernado, 2013; Karayannis et al, 2017), and as geopolymeric materials (Kalinkin et al, 2014;Huang et al, 2015). However, the presence of entrained and/or dissolved toxic metal elements, as well as the build-up of deleterious elements in the slag, is still a major constraint in the recycling and re-use of these materials.…”

“…Synthesis of functional materials from solidified slags-Metallurgical slags have a great potential as feedstocks in the production of novel functional materials such as sintered glass-ceramics (Rawlings, 1994;Gorokhovsky et al, 2002;Rawlings, Wu, and Boccaccini, 2006;Zanotto, 2010;Ponsont and Bernado, 2013;Bai et al, 2016;Liu, Zong, and Hou, 2016), porous ceramic materials (Tanaka, Yoshikawa and Suzuki, 2009;Nikitin, Kol'tsova, and Beliy, 2013;Suzuki, Tanaka, and Yamasaki, 2014;Sun and Guo, 2015), ceramic bricks (Nel and Täuber, 1970;Shih, White, and Leckei, 2006;Quijorma, San-Miguel, and Andrés, 2011;Karayannis et al, 2017), functional zeolites for waste water treatment (Kuwahara et al, 2010;Chen et al, 2012;Li et al, 2016), and refractory materials (Gu et al, 2018), among other applications. Of particular interest in the context of this paper is the synthesis of functional glass-ceramics and zeolites from metallurgical slags.…”
