I need to melt lithium carbonate and hold it between its melting point and 750 °C. Based on research so far, I think making an electrical DC-powered heater with a nichrome heating element would be best.
I have rough numbers from the link below on how much current is required depending on wire gauge etc:
In wanting to melt the lithium carbonate (1 kg or 13.53 mol), how would I work out how hot I would need to make the nichrome element? I know that the heat capacity is 97.4 J/(mol K), but I don't really know how to use the information I have.
