Materials to fabricate a high resolution plasma display back panel

A composition of materials to fabricate a high resolution, low-temperature cofired ceramic-on-metal plasma display back panel, the panel comprising a metal core having a predetermined thermal coefficient of expansion, the composition comprising a glass material formulation comprising a first glass and a second glass;

• wherein the thermal coefficient of expansion of the formulation after firing closely matches that of said metal core;
• wherein,
• said first glass includes ZnO, MgO, B2O2, and Si2, and has a formulation, by weight percent, of:
• ZnO greater than 0 to less than and equal to 30 MgO greater than 0 to less than and equal to 25 B2O3 greater than 0 to less than and equal to 20 SiO2 greater than 0 to less than and equal to 25;
• said second glass has a formulation defined by weight percent as:
• BaO 65.20-87.00 B2O3 2.60-16.10 SiO2 9.10-23.00;
• and
• said glass material has a formulation defined by weight percent as:
• first glass 89.1-65.0 second glass 10.9-35.0.
