  • Amalgam spheres for energy-saving lamps and their production
    Patent number: 9324555
    Abstract: Energy-saving lamps contain a gas filling of mercury vapor and argon in a gas discharge bulb. Amalgam spheres are used for filling the gas discharge bulb with mercury. A tin amalgam having a high proportion by weight of mercury in the range from 30 to 70% by weight is proposed. Owing to the high mercury content, the amalgam spheres have liquid amalgam phases on the surface. Coating of the spheres with a tin or tin alloy powder converts the liquid amalgam phases on the surface into a solid amalgam having a high tin content. This prevents conglutination of the amalgam spheres during storage and processing.
    Type: Grant
    Filed: June 27, 2013
    Date of Patent: April 26, 2016
    Assignee: UMICORE AG & CO. KG
