摘要： Polycrystalline alumina bodies have been converted to sapphire by a solid state conversion process in which a localized energy source is used to heat only a portion of the body to a temperature above 1800 DEG C. Using a laser as the energy source resulted in conversion to sapphire in less than an hour. The polycrystalline alumina bodies had a magnesia content below 50 wppm, an average grain size below 100 microns, and a density greater than 3.97 g/cc.

摘要： Disclosed is an electrodeless, low pressure gas discharge lamp (10). The lamp (10) includes a vitreous envelope (12) containing a metal vapour and an inert gas. The envelope (12) is shaped with an external chamber (14) for receiving an electrical excitation circuit. The excitation circuit is effective for exciting the metal vapour to emit light with electromagnetic fields that are passed through the vitreous envelope (12) from outside, to inside, the envelope (12). A circuit supplies electrical power from power mains to the excitation circuit. A transparent, electrically conductive coating (26) is disposed on the inner surface of the vitreous envelope (12) for suppressing electromagnetic interference on the power mains. An electrically conductive coating (30) is disposed on the outer surface of the vitreous envelope (12); it is capacitively coupled to the inner conductive coating (26), via a wall of the vitreous envelope (12), and is maintained at a suitable potential for suppressing electromagnetic interference on the power mains. The outer conductive coating (30) comprises a matrix (40) of a contiguous, inorganic, glass layer bonded to an exterior surface of the vitreous envelope (12), and conductive particles (42) embedded in the matrix (40) in a sufficiently dense manner to form a conductive coating.

摘要： Fused quartz diffusion tubes used in the manufacture of silicon useful for semiconductors has improved resistance to sodium diffusion by means of a metal silicate coating of a metal selected from the group consisting essentially of scandium, yttrium, beryllium, rare earth metal and mixture thereof on its surface. Although the metal silicate coating can be present on the interior or exterior surface of the tube or on both the interior and exterior surfaces, in most applications it will be present only on the exterior surface to prevent potential contamination of the silicon with a metal of the coating.

摘要： A solid state seed crystal process for bulk conversion of a polycrystalline ceramic body to a single crystal body (of the same chemical composition) having the same crystal orientation as the seed crystal. The process comprises heating said body to form a monolithic join between the body and the seed crystal, heating the joined structure to reduce grain growth inhibitors and further heating the joined structure above the minimum temperature required for crystallite growth of the crystalline material, but not hot enough to melt and distort the original shape of the polycrystalline ceramic body during its conversion to a single crystal. This process has been used to convert polycrystalline alumina (PCA) bodies to sapphire having the same crystal orientation as the seed crystal by heating the PCA body, monolithically joined to a sapphire seed crystal, at a temperature above 1700 DEG C without melting the body.

摘要： A high pressure discharge lamp includes an arc tube comprising a tubular body (388) of translucent refractory material, end walls (382) closing the ends of the body, and electrodes (390) supported in the end walls. The arc tube contains a metal halide for creating an arc plasma, the metal halide forming a molten pool during operation of the lamp. The end walls (382) are formed with an annular well (386) for containing the metal pool, and the wall (383,388) of the arc tube surrounding the well is thicker than the wall of the tubular body (388).

摘要： A ceramic discharge chamber for a lamp, according to an exemplary embodiment of the invention, comprises a first member (110) which includes a leg portion (112) and a transition portion (114), wherein the leg portion and the transition portion are integrally formed as one piece from a ceramic material, and a second member (100) which includes a body portion (102), wherein the body portion (102) is bonded to the transition portion (114) of the first member. The ceramic discharge chamber can be formed by injection molding a ceramic material to form the first member, the first member forming a first portion of the ceramic discharge chamber; and bonding the first member to a second member which forms a second portion of the ceramic discharge chamber. The members which form the ceramic discharge chamber can greatly facilitate assembly of the discharge chamber, because the discharge chamber can be constructed with only one or two bonds between the members. The reduction in the number of bonds has the advantages of expediting assembly of the discharge chamber, reducing the number of potential bond defects during manufacturing, and reducing the possibility of breakage of the discharge chamber at a bond region during handling. One or more of the members may also include a radially directed flange (115) which allows the members to be precisely aligned during assembly to improve the quality of the lamp.
