Effects of Bi2O3 and Na2O on the thermal and dielectric properties of zinc borosilicate glass for plasma display panels
An approach to select appropriate network modifiers to tailor the thermal and dielectric properties of zinc borosilicate (ZBS) glass has been explored to apply the glass composition to a dielectric layer of plasma display panels. Based on ionic field strength of the modifiers and the ionic polarizability of the corresponding crystalline form, Bi2O3 and Na2O modifiers have been selected to modify the thermal and dielectric properties of the glass toward the required properties for the application (440 < T-g < 460 degrees C, 7.5 x 10(-6)< CTE < 8.5 x 10(-6)/K, and 10 < K < 15). Bi2O3 addition to ZBS could meet all the required properties simultaneously at a given addition range (8.5-14 mol%), while the addition of Na2O could not meet all the properties at a single composition range.
