Abstract: A glass composition is disclosed that is useful as a solder glass for sealing components together. However, the glass is also especially adapted for use as an electric resistance film for coating the inner neck or funnel portions of a cathode ray tube to reduce arcing. The glass composition includes primarily the oxides of vanadium and phosphorous with the preferred addition of either zinc oxide or lead oxide. Still other metal oxides may be optionally included such as oxides of barium, antimony, lithium, manganese, silicon, boron, molybdenum and mixtures thereof.

Abstract: This invention is directed to the production of glazes exhibiting an earthenware appearance which are particularly suitable for decorating ceramic dinnerware. The glaze composition consists essentially of about 4-8% by weight SnO.sub.2 and 4-8% by weight TiO.sub.2, the total SnO.sub.2 +TiO.sub.2 being about 10-14%, and about 0.025-0.04% by weight MnO.sub.2 incorporated into a base frit consisting essentially, as analyzed in weight percent on the oxide basis, of about______________________________________ SiO.sub.2 37-49 Al.sub.2 O.sub.3 4-7 B.sub.2 O.sub.3 6.5-11 ZrO.sub.2 0-1.75 Na.sub.2 O 1.75-3.5 K.sub.2 O 0.75-2.5 PbO 21-32 CdO 0-0.75 CaO 1-9 TiO.sub.2 0-0.35 F 0-0.6 ______________________________________The fired glaze contains crystallites of rutile and cassiterite.

Abstract: This invention is directed to glazes exhibiting a strong yellow-to-brown coloration or a bright red color which are stable at temperatures of 700.degree.-950.degree. C., the latter glazes being stable in non-oxidizing or inert environments. Both glazes utilize frits consisting essentially, in weight percent on the oxide basis as calculated from the batch, of______________________________________ SiO.sub.2 35-47 B.sub.2 O.sub.3 5.5-9 BaO 24-42 TiO.sub.2 1.5-4 ZrO.sub.2 6-10 Li.sub.2 O 1-5 MgO 0-5 CaO 0-4 SrO 0-8 ZnO 0-10 Bi.sub.2 O.sub.3 0-8 SrO + MgO + CaO + ZnO + Bi.sub.2 O.sub.3 0-10 ______________________________________The yellow-to-brown coloration is produced through the addition of 0.5-10% by weight Fe.sub.2 O.sub.3 and 0-4% TiO.sub.2. The red coloration is produced through the addition of 2-10% cadmium sulfoselenide.

Abstract: A low temperature sealing glass composition consisting of 60-80% by weight of vitreous solder glass of PbO-B.sub.2 O.sub.3 system having a deformation point of 350.degree. C. or less, and 20-40% by weight of willemite. The vitreous PbO-B.sub.2 O.sub.3 system glass comprises 70-90% by weight of PbO, 10-15% by weight of B.sub.2 O.sub.3, 0.5-5% by weight of SiO.sub.2, 0-5% by weight of Al.sub.2 O.sub.3, 0-5% by weight of ZnO, 0-15% by weight of PbF.sub.2 and 0-5% by weight of Bi.sub.2 O.sub.3.

Abstract: The forming of hermetic seals suitable for sealing materials having dissimilar thermal expansions which are formed by reacting an effective amount of a metal powder, selected from the group consisting of aluminum, antimony and zirconium, with glass frit having a softening point of <750.degree. C. and a coefficient of thermal expansion sufficiently compatible with the materials being sealed to yield seals characterized by a coefficient of thermal expansion closely matching or similar to those of the materials being sealed and a use temperature equal to or greater than 1000.degree. C. The seals of this invention are particularly suitable for bonding ceramic to ceramic.
