摘要
Lightweight foamed ceramics were prepared using 55 wt.% vanadium-titanium magnetite tailings (VTMT) followed by sintering at 1130 degrees C. In the CaO-MgO-SiO2-Al2O3 foamed ceramic quaternary system, the CaO and SiO2 components play an important role in adjusting material properties and controlling phase transition. In this work, the effect of SiO2 and CaO content as additives on the tailings-based foamed ceramics properties, phase evolution, pore structure, and microstructure were systematically investigated. The results revealed that the bulk density of the samples increased with increasing CaO content. A small amount of CaO content accelerated the foaming of the samples but higher CaO contents (more than 2 wt.%) inhibited bubble growth by an increased formation of diopside (CaMgSi2O6) and other crystals with high melting temperature. Meanwhile, the amount of diopside increased from 33.56 wt.% to 74.68 wt.% with increasing CaO content, as determined by Rietveld refinement. The excessive addition of SiO2 negatively affected the number of pores, reduced pore interconnectivity, and resulted in lower average pore sizes. Moreover, samples with excessive SiO2 also displayed higher bulk density and lower open porosity. This study provides an important reference for the regulation of major chemical components for preparing solid waste-based foamed ceramics. [GRAPHICS] .
