Protective Coatings with a Mixed Composition for Low-Pressure Discharge Amalgam Lamps

摘要

The decrease of the ultraviolet radiation of high-power low-pressure discharge amalgam lamps with a protective coating with a mixed composition based on spinels and oxides has been experimentally stud ied. It has been shown that these coatings exhibit fairly high protective properties at low pressures of the buffer gas mixture and provide useful lifetime of the lamps comparable to that of the best oxide coatings.
