What is Emissivity?Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface (a black body). A black body is a material that is a perfect emitter of heat energy and has an emissivity value of 1. A material with an emissivity value of 0 would be considered a perfect thermal mirror.
For example, if an object had the potential to emit 100 units of energy but only emits 90 units in the real world, then that object would have an emissivity value of 0.90. In the real world, there are no perfect "black bodies" and very few perfect infrared mirrors so most objects have an emissivity between 0 and 1.
Accuracy of Emissivity ValuesThe accuracy of the following figures is almost impossible to guarantee as the emissivity of a surface will not only alte...
