Abstract
A ceramic arc tube having an integral susceptor for RF inductive sealing is described. The integral susceptor in the form of an electrically conductive coating is applied directly to the surface of the arc tube in the seal region. This enables RF heating which is sufficient to melt a frit material and hermetically seal the arc tube. The integral susceptor further provides for a more controlled placement of the seal.
