What material has the best emissivity?

By Bob Berry

Recent I was asked this “What material has the best emissivity?”.

It is a tricky question to answer as first I need to figure out what is meant by “best”. Best could mean, best highest, or best lowest.

Emissivity it not just a material property, it is affected by other factors.

The object with the highest emissivity is called a “blackbody”, this would have an emissivity of 1. Blackbodies however are theoretical objects. The nearest true object to this would be a blackbody simulator, these are used for calibration and would have a typical emissivity of 0.996, so almost black (not to …read more
