Title:
MATERIAL FOR REFLECTIVE MATERIAL AND REFLECTIVE MATERIAL USING THE SAME
Document Type and Number:
Japanese Patent JP2023077257
Kind Code:
A
Abstract:
To provide a low-emissivity material with high heat resistance and high oxidation resistance.SOLUTION: A material for reflective material of the present invention comprises a porous ceramics, in which the porous ceramics is composed of ceramic particles having an average particle size of 1 μm or more and 6 μm or less, and 40% or more of the ceramic particles have a particle size of 1 μm or more and 5 μm or less. An emissivity of the material for reflective material based on Kirchhoff's law in a wavelength range of 0.25 μm or more and 2.5 μm or less is 0.03 or less at 2000 K or more and 4000 K or less, and 0.06 or less at 4000 K or more and 6000 K or less is preferred.SELECTED DRAWING: None
