  • Mercury-containing material, method for producing the same and fluorescent lamp using the same
    Patent number: 6787980
    Abstract: A mercury-containing material, a method for producing the same and a fluorescent lamp using the same that can enclose a minimal amount of mercury in a glass bulb precisely, prevent flaws in a fluorescent coating while suppressing a noise during a lamp transportation, and prevent deterioration in appearance are provided. A surface of liquid mercury is coated with a continuous film made of metal oxide or metal complex oxide by dipping the mercury in a metal alkoxide solution and then heating the mercury on which the metal alkoxide solution adheres. Accordingly, the minimal amount of the mercury can be enclosed in the fluorescent lamp precisely, thus achieving friendliness to the environment. It also is possible to prevent flaws in the fluorescent coating while suppressing a noise during the lamp transportation and further to prevent deterioration in appearance.
