    Abstract: A high pressure discharge lamp utilizing an improved ceramic arctube (20). The arctube has a ceramic central portion (22), a first ceramic leg (24a) extending from one end of the central portion and in some embodiments a second ceramic leg (24b) extending from the other end of the central portion. The arctube has reinforcing means (26a,26b) where one or both of the legs joins the central portion to reinforce and strengthen the connection between each leg and the central portion. The reinforcing means is preferably seal glass or a layer of seal glass adjacent a ceramic ring.

    Abstract: A solid state process for the bulk conversion of a dense polycrystalline ceramic body to a single crystal body has been accomplished by heating the polycrystalline material to a temperature above one-half of the melting temperature of the material but below the melting point of the material. As the process is a solid state process, no melting of the ceramic body is necessary to convert it to a single crystal. The process has been used to convert a dense polycrystalline alumina body (PCA) containing less than 100 wppm of magnesia to sapphire (single crystal alumina) by heating the PCA to temperatures above 1100°C but below 2050°C, the melting point of alumina.

    Abstract translation: 通过将多晶材料加热到材料的熔融温度的一半以上但低于材料的熔点的温度，已经实现了将致密多晶陶瓷体大量转化成单晶体的固态方法。 由于该方法是固态工艺，因此不需要熔化陶瓷体以将其转化为单晶。 该方法已被用于通过将PCA加热至高于1100℃但低于2050℃的温度将氧化铝含量低于100wppm的致密多晶氧化铝体（PCA）转化为蓝宝石（单晶氧化铝），氧化铝的熔点 。

    Abstract: This lamp comprises (1) an envelope of vitreous light-transmitting material enclosing an internal space where light is generated and (ii) conductive lead structure projecting into said internal space. Surrounding and sealed to said lead structure is a body of vitreous material formed of particles of vitreous material pressed together and sintered. This body extends through an opening in the envelope that communicates with said internal space. A hermetic seal is provided between said envelope and said body in the interface region between said envelope and said body.
    A method of manufacture for the lamp involves making up, separate from the envelope, a subassembly comprising said lead structure and said vitreous body that surrounds it. In one form of this method, particles of vitreous material are pressed into a mold cavity that surrounds the lead structure, thus forming a compact surrounding the lead structure. This compact is sintered in an inert atmosphere, thereby forming the subassembly. Thereafter, the subassembly is placed in the opening in the envelope, and the hermetic seal is made between said envelope and said vitreous body in the interface region between said envelope and said vitreous body.
