High emissivity stickers
WebObtaining total hemispherical emissivity at high temperatures is difficult. Typically only directional data at specific viewing angles (normal, near normal or at an angle between 45 and 60 degrees) is generated at high temperatures. The calculation of hemispherical emissivity from the directional emissivity is an approximation. Web1 de jul. de 2009 · The infrared emissivity in 2.5–25 μm of LDC coatings was enhanced with the increase of La concentration at high temperature 873–1273 K. Compared to the undoped CeO 2 coating, the infrared emissivity of 16.7% LDC coating increases by 55%, and reaches up to 0.9 at 873 K.
