Graphite melting temperature
WebGraphite can melt but it takes a temperature of 3,600 degrees Celsius or 6512 degrees Fahrenheit to do so. If you were observing the process waiting for liquid carbon to emerge, you would be very disappointed. Can It Boil? WebNov 10, 1998 · ABSTRACT A subsecond laser heating technique has been successfully applied for graphite melting under controlled isobaric conditions. During the applied pulses, relatively large amounts of graphite were melted and subsequently solidified under good stability conditions of the liquid mass. The solid–liquid-vapor triple point was determined.
