Dear all I have 250g of Copper 250g of Tin and 250g of Sulfur. Everything is in powdered form. Heated up in closed container wit surrounding nitrogen flow to avoid contact with Oxygen. Heating ramp is 3 hours to 1000K. What reaction will be the leading reaction? How to calculate how fast will S react with Metals and at what temperatures? If there is excess of sulfur - in what form will it leave the vessel - S4, S8? I am afraid that there will be huge formation of sulfur vapor and it can damage the oven and everything else. I am still searching for a good book on Sulfur Chemistry and process engineering. If there is a good literature - please advise.
