Embodiment

[0055] The raw materials were mixed and the result was a composition as shown in the rows PbO to MgO or CoO in Table 1 or 2 (in mass percent). Then, the mixture was melted by a platinum crucible in an electric furnace at 1200-1350° C. for 1 hour. Then, this piece of glass was pulverized by a ball mill to obtain glass powder. Examples 1-12 represent examples of the invention.

[0056] For the glass powders of Examples 1-12, Ts (unit: °C), α (unit: 10 -7 / °C), ε, T 550 ' (unit: %) and turbidity (unit: %).

Abstract

A glass for covering electrodes, which consists, as represented by mass percentage based on the following oxides, essentially of from 35 to 55% of PbO, from 15 to 30% of B2O3, from 4 to 15% of SiO2, from 20 to 44% of B2O3+SiO2, from 0.5 to 10% of TiO2+ZrO2+La2O3+Ta2O5, from 0 to 15% of Al2O3, from 0 to 25% of BaO, from 0 to 1% of CuO and from 0 to 1% of CeO2.

Description

technical field [0001] The present invention relates to a low-melting-point glass, colored powder and plasma display, said low-melting-point glass is suitable for insulating covering transparent electrodes, especially transparent electrodes having silver electrodes formed on their surface parts, said transparent electrodes are made of, for example, ITO (indium oxide doped with tin) or tin oxide. technical background [0002] In recent years, thin flat panel color displays have attracted attention. In such a display, it is necessary to form an electrode of each pixel to control a display state in the pixel for forming an image. In order to prevent deterioration of image quality, transparent electrodes are used as such electrodes. As for the transparent electrode, an ITO or tin oxide thin film formed on a glass substrate is generally used. [0003] A transparent electrode is formed on the surface of the glass substrate used as the display screen of the above-mentioned displ...
