Ceramic-Coated Emitter Withstands the Heat (2 of 2)

Caption: This cross-section micrographs of a tungsten thermal emitter used in the experiment. Figure 2a shows how unprotected tungsten degrades after heating to 1200 degrees Celsius. Fig. 2b demonstrates how the ceramic-coated tungsten retained structural integrity after being subjected to 1400 C heat for an hour.
