Abstract: TiO2/SiO2 hybrid film, having water resistance, for water purification photocatalyst was successfully and firmly coated on stainless steel with one dip coating and heat curing method. By controlling relative content of the TiO2 sol and the SiO2 based binder, these films were found to have a significant influence on the hardness, water-resistance, and photocatalytic activity.

Abstract: The effect of RO components variation on some properties was studied in Pb free glass frit for PDP (Plasma Display Panel). One of the main components, BaO, was replaced progressively at fixed concentration of alkaline earth oxides. We studied the transparency, thermal expansion, softening point, and the high temperature microscopic behaviors of glass frits and TG(thermal gravimetry) of raw material. The compositional dependence of those properties was discussed from the view points of compositional diversity and production process of Pb free glass frit.
