Title:
ELECTROMAGNETIC WAVE ABSORBING MATERIAL
Document Type and Number:
Japanese Patent JP2004177420
Kind Code:
A
Abstract:
To provide an electromagnetic wave absorbing material which efficiently absorb light of wide wavelength range from ultraviolet ray to near-infrared ray or further to far-infrared ray.
The electromagnetic wave absorbing material contains ferrous oxide and further can contain a holding material (a resin, a rubber raw material, cement, clay or the like). Absorbing ratio (emissivity) of the electromagnetic wave absorbing material is ≥90% to light of wide wavelength range from ultraviolet ray to near-infrared ray or further to far-infrared ray.
