EMISSIVITY Emissivity adjustment is optional. Emissivity adjustments are used to provide a truer temperature reading. Different materials radiate infrared energy at slightly different temperatures. The emissivity adjustment is used to compensate for different types of materials. The default emissivity of 0.95 will cover 90% of typical applications.
The emissivity value determined was 0.426 at 0.652 μm. Aution and Scala Price [2] measured the spectral normal emissivity of single crystal zirconium at 1063 K and the average emissivity of basal and prismatic faces was found to decrease with increasing wavelength although peaks in emissivity were found between 2 and 3 μm and at 7 μm.

Zircon . Zircon makes a nice gem but it's out of favor these days. Zircon—zirconium silicate or ZrSiO 4 —is a hard stone, ranking 7½ on the Mohs scale, but other stones are harder and its colors aren't unique.Tradition has a slim dossier on zircon; one site says that it was reputed to "aid sleep, bring prosperity, and promote honor and wisdom," but hey, …
Introduction. The emissivity control of various materials has been exploited in several technical fields [1]. An important application is that the low-emissivity materials can be used in civil and military fields, such as energy conservation in industry field or camouflaging military equipment or vehicles from infrared detection in military field [2], [3].
Zirconium silicate is a high-quality and inexpensive opacifier, which is widely used in various architectural ceramics, sanitary ceramics, daily-use ceramics, and first-class ceramics.
