Sintering Distortion of Barrier Ribs Formed via Capillary Molding
Tea-Jung Chang, Sang H. Yoon, Yong Seog Kim · Materials science forum · 2004
Various closed-cells of plasma display panel were prepared via capillary moldingof paste containing ceramic powders of barrier ribs. The cells include meander, honeycomb, waffle and SDR. In this study, the sintering behaviors of such barrier ribs were investigated. The effects of pre-firing temperature, solid content in the paste, and type of cells on morphologies of the ribs were examined. The results indicated that cells with asymmetric geometry such as SDR and meander results in severe distortion after the sintering. The cells with symmetric geometry such as waffle and honeycomb, on the other hand, the distortion was negligible. Using the waffle type cells, the luminance characteristics of PDP device were evaluated.
