Electrode-coating glass composition, coating for forming electrode-coating glass, and plasma display panel using the same and its manufacturing method

Abstract

An electrode-coating glass composition of the present invention satisfies −9.5≦A≦−4, 3000≦B≦3900 and 240≦C≦320 in Fulcher's equation log η=A+B/(T−C), which defines the temperature (T[° C.]) dependence of viscosity (η[dPa.s]). Furthermore, the absolute value |Δ log η| of the difference between values of log η at temperatures of 50° C. above and below a softening point is at least 4.2. Such an electrode-coating glass composition can be achieved, for example, by a glass composition containing at least one of BaO and Al2O3, and 40 to 66 wt % of PbO, 2 to 25 wt % of SiO2, 5 to 40 wt % of B2O3, 0 to 20 wt % of BaO, 0 to 8 wt % of Al2O3, 0 to 2 wt % of CuO, and 0 to 2 wt % of CeO2.
