(Q) Can heat in the far-infrared rays metal? (A) Since there is a lot of metal electrons, it reflects the electromagnetic waves (far-infrared rays) in general. The good conductivity metal such as gold and aluminum, it is hard to heating ...

(1) Infrared Rays are subdivided into several scheme. ISO 20473 specifies the following scheme: Designation Abbreviation Wavelength Near-Infrared NIR 0.78–3 µm Mid-Infrared MIR 3–50 µm Far-Infrared FIR 50–1000 µm (2) Difference in frequency = The difference between the heating capacity By “Wien’s displacement ...

The method of heating the ceramic to make a far-infrared artificially is common. The fine ceramics of an alumina system or a zirconium system are used well. Wavelength and the emittance change by a kind and the heating temperature of ...

  【 Infrared Absorption Rate 】 Please confirm the index of absorption of infrared rays in this table. The material absorbed by about 0.5 = 50% or more is suitable for the infrared heating.

1.Planck Radiation Law Max Karl Ernst Ludwig Planck, FRS (23 April 1858 – 4 October 1947) Planck’s law describes the electromagnetic radiation emitted by a black body in thermal equilibrium at a definite temperature. The law is named after Max ...

The thermal energy transfer from higher temperature to lower temperature. Transfer of the thermal energy , there are three principles, Conduction, Convection, and Radiation. In an actual situation, transfer of the thermal energy is performed in the form these three ...

Infrared Rays are subdivided into several scheme. ISO 20473 specifies the following scheme: Designation Abbreviation Wavelength Near-Infrared NIR 0.78–3 µm Mid-Infrared MIR 3–50 µm Far-Infrared FIR 50–1000 µm The International Commission on Illumination (CIE) recommended the division of infrared radiation into the following ...

Although it is not visible, because the light with the power which warms a thing existed “outside red”, it was named “infrared rays.” Infrared rays are the same “Electromagnetic waves” as “X-rays”, “Ultraviolet rays”, “Visible light”, “Microwave”, “Radiofrequency wave”, etc. ...
