The influence of co‐additions of crystalline TiO 2 and SiO 2 fillers (10 wt% addition in total) to BaO–ZnO–B 2 O 3 –SiO 2 glass on resultant properties was investigated from the viewpoint of applying the material to the barrier ribs of plasma display panels. The substitution of SiO 2 for TiO 2 reduced the dielectric constant significantly, while it maintained high optical reflectance and appropriate coefficient of thermal expansion (CTE) in the case when TiO 2 alone was used. A 5–7.5 wt% SiO 2 addition with 2.5–5 wt% TiO 2 under the constraint of 10 wt% total fillers demonstrated an optical reflectance of about 55%, a CTE of about 8.3 × 10 −6 K −1 (compatible with glass panels), and a dielectric constant of about 7.5, which are promising properties for the barrier rib application.
