摘要:
Inorganic powder as a plasma display panel material comprises a powdery material containing glass powder. The powdery material has a moisture content adjusted to fall within a range between 0.1 and 2 mass %. The powdery material may include the glass powder alone or may further comprise ceramics powder in addition to the glass powder. The inorganic powder may be used as a paste or a green sheet.
摘要:
A dielectric forming material for use as a transparent dielectric layer formed on an inside surface of a front glass substrate in a plasma display panel comprises powder of colored glass. The powder of colored glass comprises a base glass and coloring ingredients added thereto. The coloring ingredients comprise CoO and NiO. The powder of colored glass provides a glass film having a spectral transmittance T%(460 nm) of 50-75% at the wavelength of 460 nm or a glass film having a spectral transmittance T%(460 nm) higher than a spectral transmittance T%(550 nm) at the wavelength of 550 nm and a spectral transmittance T%(620 nm) at the wavelength of 620 nm. The glass film is formed by applying the colored glass powder onto a soda lime glass plate having a thickness of 1.7 mm and by baking the colored glass powder to form a baked film having a thickness of 20-40 &mgr;m as the glass film.
