According to its X-ray powder diffraction(XRD)analysis results(Fig.2),the as-received SPL from an aluminum smelter contained mainly graphite,Na F,nepheline(Na Al Si O4),Na2O(Al2O3)11,and silicon(Si).Its chemical composition is listed in Table 1.The presence of Si is possibly due to the reduction of the siliceous refractory components in the highly reductive environment present in the Al electrolytic cells.
