Title:
REFLECTOR, METHOD FOR MANUFACTURING THE REFLECTOR, AND HEATER UNIT AND FURNACE USING THE REFLECTOR
Document Type and Number:
WIPO Patent Application WO/2007/145234
Kind Code:
A1
Abstract:
Provided is a reflector which can maintain reflection performance even in a high-temperature
atmosphere, has excellent reflection wavelength characteristics and can be
manufactured at a low cost. A method for manufacturing such reflector, and a
heater unit and a furnace using such reflector are also provided. One side of
a base material, such as steel material or ceramics, is coated with a noble metal
layer through an intermediate layer. Heat rays are reflected by the noble metal
layer. The one side of the base material faces a high temperature atmosphere,
and an intermediate layer (3b) is composed of frit. The thickness of the intermediate
layer (3b) can eliminate a difference between the thermal expansion of the noble
metal layer (3c) and that of the base material (3a) in the high temperature atmosphere
and maintain the noble metal layer (3c).
