Abstract
In infrared radiators whose heater is disposed in an envelope tube of transparent or opaque fused vitreous silica, radiation losses can be reduced by a reflective coating, for example of gold, placed on the envelope tube. To improve the thermal stability of the reflective coating, a protective coating of zirconium, silicon and/or tin dioxide is proposed. The protective coating can be made by using thermally degradable organic zirconium, silicon and/or tin compounds.
