REFLECTIVE COATING FOR GAS-DISCHARGE LIGHT SOURCES
(pp. 62-64)

Abstract. Developed by the authors reflective coating relates to the field of vacuum, electronic and electrical industry and can be used in metal halide (IPF) or sulfuric superhigh-frequency (SHF) lamps. Analysis and experience with reflective coatings showed that the basis of the coverage must be silicon dioxide. Heatresistant dye, which represents an oxide of chromium, still performs the role of selectively reflecting radiation of the discharge. Other components must be stable at high temperatures, inert in an oxidizing environment (air), to have good adhesion, to have similar coefficients of linear thermal expansion, as well as the possibility of formation of the eutectic. The purpose of this study is to improve adhesion reflective coatings at high temperature in an oxidizing atmosphere. Proposed to achieve this goal optionally type the following components satisfying the above requirements: zirconium oxide, beryllium oxide, yttrium oxide, magnesium oxide. Magnesium oxide is responsible in the preparation of the composition of reflective coatings for the creation, together with other oxides, eutectic, should have the relevant technology, and the rest of the oxides, at a certain process, provide the required functionality. Theoretically calculate the composition is impossible, so the percentage of components was calculated experimentally. For determining the composition of the reflective coatings were tested standard quartz burners lamps DRI – 250.
