Abstract
A metallized spinel material and a method for producing a metallized spinel material are provided. The spinel is a high-transmissive material and, particularly, has high transmission in the ultraviolet and, preferably, the visible infrared wavelength regions as well. The high-transmissivity spinel material is metallized by applying the slurry containing a metal, such as tungsten, molybdenum and/or manganese to the substrate, and firing at en elevated temperature such as 1200.degree. to 1800.degree. C., preferably 1500.degree. to 1800.degree. C. for about 1/2 hour in a non-oxidizing atmosphere.
