Heating of sulphur powder
Web8 de abr. de 2024 · Sulphur's melting point is lower than that of iron. As a result, when we heat the iron filings and sulphur powder mixture, the sulphur melts first. The melted sulphur combines with the iron fillings in the mixture to generate the chemical compound iron sulphide, which is black in colour. Chemical equation: F e + S = F e S. Additional … Web6 de may. de 2024 · TB-Briquette, WS-Briquette, TB-Powder and WS-Powder were used in this section. As shown in Figure 4a,b, when the reaction temperature is 800 ∘ C, the difference of SO 2 release amount between the powder samples and the briquettes samples is negligible. That is due to the sulphur starting to release after 800 ∘ C.
