ABSTRACT:
The quartz tubes of the heating elements of an infrared oven have a limited portion of their circumference coated with a mixture containing platinum. The platinum coating provides a reflective surface to direct infrared radiation towards the object to be heated within the oven. The heating element tubes coated with platinum provide substantially the same performance and are significantly less expensive to manufacture than conventional heating element tubes with a gold reflective coating.
