Abstract: A fusible spacer (10) for use in the manufacture of a plasma panel rigidly maintains a preselected spacing between the panel sidewalls (12, 14). The fusible spacer (10) comprises a core (40) 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 (12, 14). A cladding (42) surrounds the core (40) along and is formed from a material which has a much lower softening point, i.e., 350`C to 500`C. In the manufacture of a plasma panel the fusible spacers (10) are positioned on one sidewall (12) at a number of separate locations. The second sidewall (14) is then positioned on the first sidewall (12) and the composite panel is raised to a temperature sufficiently high to cause a softening of the solder glass cladding (42) fusing the two sidewalls (12, 14) together at a number of locations. Accordingly, the separation between the two halves of the panel is set by the first dimension of the core member (40) while the solder glass cladding (42) rigidly attaches to both panel sidewalls (12, 14) bonding the composite structure together. The core member (40) 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 (16, 18).
