Temperature of molten gold
WebThe melting point of gold is 1,064 degrees Celsius or 1,943 degrees Fahrenheit. This is one of the highest melting points of any metal, and it is because of this resistance to heat – as well as its conductivity – that gold is used so prolifically in electronics. This means all of our gold bars and gold coins do not have any additional VAT ch… Bullion dealers often list their gold and silver coins as being of varying conditions … Web31 Jul 2011 · The reported temperature coefficient, in the temperature range 1498–1603 K, of molten gold is − 0.14 [35], [36], −0.20 [40]and − 0.19 mJ/m2 K [43]. The value obtained in our study (− 0.1773 mJ/m2 K), in the same temperature range, compares remarkably well with the mean value published by others.
