  • Filament for infrared lamp and method of manufacturing the same
    Patent number: 8133088
    Abstract: The present invention relates to a filament for an infrared lamp used as a heater and a method of manufacturing the same. The method of fabricating the filament includes cutting a thin graphite plate into a thin graphite plate strip of a predetermined size, integrally adhering two sheets of the thin graphite plate strips using heat, primarily heating and plasticizing the integrally adhered graphite plate strips within an inert gas, coating a silicon-series coating solution on the primarily heated and plasticized graphite plate strips and naturally drying the graphite plate strips, and heating and plasticizing the naturally dried graphite plate strips using an identical process to the primary plasticity process and then naturally cooling the heated and plasticized graphite plate strips.
    Type: Grant
