摘要： There is described a sealing composition for sealing aluminum nitride and aluminum oxynitride ceramics comprising: a mixture of SiO2, at least one other metal oxide, and a silicon additive comprising at least one of silicon metal or a silicide. The silicon additive acts to suppress the formation of nitrogen bubbles during the sealing of articles comprised of aluminum nitride or aluminum oxynitride ceramics, e.g., as in the case of a ceramic discharge vessel for a high intensity discharge lamp.

摘要： The present invention is a ceramic discharge vessel for use in high-intensity-discharge (HID) lamps. The discharge vessel has a ceramic body and at least one seal region comprised of an aluminum oxynitride material. The seal region further has a surface layer for contacting a frit material wherein the surface layer is less reactive than the aluminum oxynitride material with respect to the molten frit during sealing. Preferably, the surface layer has a lower nitrogen content than the aluminum oxynitride material. The less reactive surface acts to minimize the formation of bubbles in the sealing frit during the sealing operation.

摘要： A method of producing a ceramic metal halide discharge lamp having a monolithic seal between a sapphire (single crystal alumina) arc tube and a polycrystalline alumina (PCA) end cap. The method includes the steps of providing an arc tube of fully dense sapphire and providing an end cap made of unsintered compressed polycrystalline alumina powder doped with magnesium oxide and yttrium oxide. The end cap is heated until it is presintered to remove organic binder material at a low temperature relative to the sintering temperature. The presintered end cap is placed on an end portion of the arc tube to form a close interface between the two. The presintered end cap and adjacent arc tube are then heated to until the end cap is fully sintered onto the arc tube and the sapphire tube grows into the end cap. A monolithic seal is formed along the interface between the end cap and the arc tube as the sapphire tube grows into the polycrystalline alumina end cap. The yttrium oxide promotes increased growth between sapphire tube and the PCA end cap and is not detrimental to the metal halide chemistry, nor subject to erosion by the metal halide chemistry.

摘要： A new and improved bonded ceramic-metal article and the method of making the article is described. The ceramic-metal article comprises a ceramic article, such as a lanthana-strengthened yttria article, bonded to a metal article, such as niobium, by a layer of a brazing material to form a bonded ceramic-metal article. The method of bonding the ceramic article to the metal article comprises placing the brazing alloy, such as a brazing alloy consisting essentially of 63% by weight silver, 35.25% by weight copper, and 1.75% by weight titanium, between the lanthana-strengthened yttria article and the niobium article and heating the layered structure in vacuum at about 50 degrees centigrade above the liquidus temperature of the brazing alloy for a period of about 5 minutes. Another method of bonding the ceramic article comprises coating a surface of the lanthana-strengthened yttria article with a group IVB metal, such as titanium, hafnium, and zirconium then placing a different brazing alloy, such as a brazing alloy consisting essentially of 72% by weight silver and 28% by weight copper or a brazing alloy consisting essentially of 82% by weight gold and 18% by weight nickel, between the coated lanthana-strengthened yttria article and the niobium article and heating the layered structure in vacuum at about 50 degrees centigrade above the liquidus temperature of the brazing alloy for a period of about 5 minutes.
