Abstract

Carbon-glass composite powders were directly prepared by spray pyrolysis from spray solution containing nano-sized carbon black powders and dissolved Pb-based glass components. The composite powders had spherical shape and non-aggregation characteristics. One composite particle was formed from one droplet. The mean size of the composite powders measured from the SEM images was 0.7 μm. Carbon black powders were well dispersed inside the matrix of glass. The black matrix layers formed from the carbon-glass composite powders had smooth surfaces at firing temperatures of 500 and 550°C. The black matrix layers formed from the paste with carbon-glass composite powders had lower transmittances than those formed from the paste with carbon black and glass powders under ultraviolet and visible light range. The reflectances of the black matrix layers formed from the paste with carbon-glass composite powders were 3.1 and 4.3% at firing temperatures of 500 and 550°C.
