I am looking for data on the total hemispherical emissivitie from a Platinum surface at high temperature 1400 - 2000 K. In this temperature range the Platnium surface will color from red, orange to white.
I learned that, practically, the bove mentioned emissivity will approach to one in this temperature range.
Platinum has a low emissivity at room temperature: something between 0.1 and 0.2 (as most website tables how). Does the emissivity of this metal go to 1 when white hot?
Materialquality of Platinum is shiny.
