Abstract (en)
[origin: EP0465759A2] In infrared emitters, whose resistance wire is located in a sheathing tube of quartz glass or fused silica, radiant losses can be reduced by means of a reflection layer, for example of gold, located on the sheathing tube. To improve the thermal stability of the reflection layer, a protective coating of zirconium dioxide, silica and/or tin dioxide is proposed. The protective coating can be produced by using thermally decomposable organic compounds of zirconium, silicon and/or tin.
