PDP 용 격벽 페이스트에 사용되는 Pb Free 유리 조성물에 관한 연구

A Study on the Lead Free Ceramic Frits for Rip Paste of Plasma Display Panel

Recent great development in various electronic industries such as display, low temperature co-fired ceramic(LTCC), and packaging industry need new various glasses which satisfies the specific requirements. PbO containing glass systems are popular as a commercial low temperature and good thermal and electrical characteristics. However, recent nature protection issues have restricted the wide use of PbO systems, so the development of lead free materials, which can replace the PbO, has been undertaken. in this study Bi based glass frit was developed in PDP applications and its properties are compared with the commercially used Pb based glass frit. After optimization. of the properties of Bi based frits for PDP application such as the softening temperature and coefficient of thermal expansion(C.T.E).
