Chat Online· The chemical oxide composition of the collected ash and slags is given in Table 5. The oxide content is the smallest in the floating slag sample. The main elements are given as oxides. Among these oxide compounds there is a relative high content of magnesium and calcium oxides which justifies the low melting points of this material. The laid down slag and the fly ash samples present a higher content in silicon and aluminium oxides than the floating slag.
