New Vacuum Furnace Turns Metal Samples Into Their Own Heaters to Measure Emissivity Past 3,000 Degrees
Researchers have built a vacuum-compatible system that uses direct electric heating to measure the spectral emissivity of refractory metals from 500 to over 3,000 degrees Celsius with uncertainty below 2 percent.
