Patent ID: 7012372

Claim:
An electrode-coating glass composition, wherein an absolute value |Δlogη| of a difference between values of logη at temperatures of 500° C. above and below a softening point is at least 4.2, where η is a viscosity of a glass, the viscosity η is measured in [dPa·s] units, wherein the glass composition has a total transmittance of at least 85% and comprises: at least one of barium oxide (BaO) and aluminum oxide (Al 2 O 3 ); 40 to 66 wt % of lead oxide (PbO), 2 to 25 wt % of silicon dioxide (SiO 2 ), 5 to 40 wt % of boron trioxide (B 2 O 3 ), 0 to 20 wt % of barium oxide (BaO), 0 to 8 wt % of aluminum oxide (Al 2 O 3 ), 0 to 2 wt % of copper oxide (CuO), 0 to 2 wt % of ceric oxide (CeO 2 ), and does not contain calcium oxide (CaO) or magnesium oxide (MgO), and the glass composition is in a powder form, further comprising: a solvent; and a binder resing, and wherein the glass powder has a maximal particle size of not more than 16 μm and a particle size distribution with its peaks in ranges of 0.9 to 1.3 μm and 5 to 6 μm.
