摘要： Internal arcing in a cathode ray tube is substantially prevented by coating a portion of the interior of the funnel and neck of the tube with an electrically conductive composition, and coating a portion of the interior of the funnel and neck of the tube with an electrically resistive composition. The electrically conductive composition comprises about 10-30 weight percent iron and about 90-70 weight percent of a glass frit. The electrically resistive composition comprises about 8-24 weight percent iron, about 2-8 weight percent TiO.sub.2 and about 90-68 weight percent glass frit. The use of conventional "dag" coatings is eliminated. The cathode ray tube is especially useful as a picture tube in a color television receiver in which high operating voltages are employed.

摘要： A sealing glass and a sealing glass paste for sealing the face plate and funnel portion of a color television tube wherein PbO-containing sealing glass frit contains from an effective amount of a powder, such as Pb.sub.3 O.sub.4 powder, which powder prevents the reduction of PbO to Pb metal during the sealing process, which reduction would otherwise result in a dielectric breakdown in the seal. A sealing glass paste consisting essentially of a PbO--B.sub.2 O.sub.3 --ZnO sealing glass frit and containing an effective amount of said powder, based upon the weight of the frit, together with hydroxypropyl cellulose binder for the frit and a solvent for the binder. A method for sealing the face plate of a color television tube to its funnel portion with a PbO-containing solder glass wherein the reduction of PbO to metallic lead during the sealing step is obviated by the addition of a sufficient amount of Pb.sub.3 O.sub.4 or BaO.sub.2 powder in the solder glass and paste made therewith, which Pb.sub.3 O.sub.4 or BaO.sub.2 is slowly reduced to a lower oxide in a reducing atmosphere during the sealing of the television tube components. A method for increasing the dielectric properties of a PbO-containing sealing glass paste and the devitrified seal made therefrom, which seals the face plate to the funnel of a color television tube, to a value greater than that provided by the solder glass, per se, by incorporating in the solder glass and the solder glass paste made therefrom a small but sufficient amount of Pb.sub.3 O.sub.4 or BaO.sub.2 to accomplish this purpose. A vehicle for a glass frit comprises hydroxypropyl cellulose as a binder and a solvent for said binder.

摘要： Disclosed is a physical blend of particulate lead borate sealing glass and particulate refractory filler for use in forming thermal fusion seals for workpieces having a lower coefficient of thermal expansion than the sealing glass. The particulate refractory filler has a particle size diameter in excess of about 37 microns (i.e. plus 400 U.S. Sieve) to lower the expansion while maintaining adequate flow during fusion. The blend is especially useful as a package sealant for electronic components.

摘要： A composite glass article having a chemically modified ceramic surface whose coefficient of thermal expansion is lower than that of the glass substrate is produced by exposing the glass article maintained at a temperature above its annealing point (typically 500.degree. C.) and below its softening point (soda-lime about 725.degree. C.; borosilicate about 800.degree. C.) to an atmosphere containing prescribed metalorganic compounds. The chemically modified ceramic surface in maintained in compression and is a ceramic consisting of members from a specific group of oxides dependent upon the type of glass comprising the substrate. The method for forming the glass composite article includes applying the metalorganic mixture while the glass substrate is maintained at a temperature above its annealing point (typically 500.degree. C.) and below its softening point (sodalime about 725.degree. C.; borosilicate about 800.degree. C.) to an atmosphere containing prescribed metalorganic compounds. A chemical reaction occurs producing a chemically modified ceramic coating which is in compression relative to the substrate thus conferring increased strength to the glass article.
