Colored glass frit

摘要

A colored glass frit with a specific surface area of less than 2 square meters per gram that contains from about 1 to about 80 weight percent of metallic element material and from about 30 to about 80 mole percent of glassy network forming oxide material. The frit has a transmission density per micron of thickness of at least about 0.1; when formed into a continuous film of 3 microns thickness and deposited onto a glass substrate, its transmission density is at least 0.3. The glassy network forming oxide material is homogeneously disposed in the flit, and the metallic element material is inhomogeneously dispersed within the glassy network forming oxide material. The metallic element material is in particulate form and has a particle size distribution such that at least 95 weight percent of its particles are smaller than 300 nanometers.
