ABSTRACT

Dielectric layer of phosphate glass for plasma display panel (PDP) device made by silk screen printing on soda-lime glass. For regulate thermal expansion coefficient (CTE) of between substrate glass and dielectric layer use adition ofAl2O3 and TiO2. The crystallization process of glass-ceramics for dielectric layer have been examined by DTA, XRD someThe principal crystalline phase was identified as zinc metaphosphate [Zn(PO3)2] and zinc pyrophosphate [Zn2P2O7].Reflectance and dielectric constance increased with the addition of TiO2 filler, dielectric constant lower the out sidereflectance unchanging of the adding of Al2O3 filler. Besides CTE was at about 62×107/oC.Key words Phosphate glas, Plasma display panel, Crystallization, Glass-ceramics, Dielectric layer, Zinc metaphosphate,Zinc pyrophosphate, Dielectric constantAC-PDP. ... ... ... ... ... .. ....... ...†..... ...... , .. , 520-714(2007. 4. 3. .. )(2007. 6. 8. .... ). . .... ... ....
