| Abstract |
| The dielectric layers for plasma panel display device were prepared from two series of glass-ceramics, namely, P₂O_5-ZnO-BaO and SiO₂-ZnO-B₂O₃ glass-ceramics containing filler. The nucleation and crystallization process of glassceramics for dielectric layer have been examined by differential thermal analysis, X-ray diffraction and light and electron microscopy. Optical, thermal and electrical properties of the dielectric layer were evaluated by means of spectrophotometer, dilatometer and LCR meter. From this research, it was found that these glass-ceramics are useful materials for dielectric layers in plasma panel display device, as those have a similar thermal expansion to soda-lime glass plate, high reflectance, low sintering temperature. Also the addition of Al₂O₃ and TiO₂ as fillers to these glass-ceramics is considered to be suitable for acquiring good properties of dielectric layer for PDP device. |
