ABSTRACT:
A fusible spacer for use in the manufacture of a plasma panel rigidly maintains a preselected spacing between the panel sidewalls. The fusible spacer comprises a core fabricated from a refractory glass, such as R-6 glass, and has a first transverse dimension sized in accordance with the desired spacing between the panel sidewalls. A cladding surrounds the core along and is formed from a material which has a much lower softening point, i.e., 350.degree. C. to 500.degree. C. The separation between the two halves of the panel is set by the first dimension of the core member while the solder glass cladding is fused to rigidly attach to both panel sidewalls bonding the composite structure together. The core and fusible cladding are drawn to size by covering the cladding with a second transitory cladding of the same material as the core material to allow a dimensionally controlled fiber to be drawn even through the fusible cladding has a substantially lower softening point. The core member can have a circular cross section or numerous other cross sections so long as the first transverse dimension defines the panel spacing and the second transverse dimension is not too large to interfere with the discharge sites between row and column electrodes.
