Abstract: A joint structure jointing a ceramic member and a metal member is a joint structure jointing a ceramic member and a metal member that are provided in a device provided on a portion through which gas passes. The joint structure has a joint portion that joints the ceramic member and the metal member. The joint portion includes a glass portion made of a glass and a metal solder portion having higher corrosion resistance with respect to the gas than the glass. An area where the metal solder portion contacts to the gas is larger than an area where the glass portion contacts to the gas.

Abstract: The invention reflects discovery of a liquid phase doping technique that, unlike previous techniques, exhibits very little fluorine depletion upon subsequent heating. The invention involves the steps of providing a silica sol comprising a tetraalkylammonium hydroxide and a di-, tri-, or tetraalkylammonium fluoride, the sol having pH of about 10 to about 14, adding a gelling agent to the sol to induce gelation, casting or extruding the sol to form a gel body, and then drying, heat treating, and sintering the body. Advantageously, the fluorine-containing compound is tetramethylammonium fluoride.

Abstract: An improved sol-gel process is disclosed for the making of large synthetic silica based bioactive materials objects crack-free. A series of ordered mesoporous SiO2—CaO—P2O5 sol-gel glasses which are highly bioactive are synthesized through a sol-gel process. The mesoporous glasses are highly bioactive compared with conventional ones, due to the increased textural characteristics, i.e. surface area. The bioactivity tests point out that the surface area, porosity, and 3D-structure become more important than chemical composition during the apatite crystallization stage in these materials, due to the very high textural parameters obtained. The product is intended to be used for tissue engineering applications.

Abstract: A process for manufacturing glass bodies of doped silicate glass is disclosed. The process involves flame hydrolysis, wherein precursors for the forming of the doped glass are fed together with fuel gases into a single burner. A first formed body is generated on a target. The doped silicate glass produced in this way offers a low density of defects and a small breadth of striae. Preferably the first formed body is subsequently formed into a second formed body having a larger breadth and a smaller length than the first formed body. Thereby, the breadth of striae and the density of defects in the doped silica glass is further reduced.

Abstract: Glass or ceramic products including glass optical waveguides are produced by a vapor phase oxidation process wherein .beta.-diketonate complexes of selected metals having significant vapor pressures at some temperature below their decomposition temperatures are vaporized, transported to an oxidation site in the vapor phase, and reacted in the vapor phase to form particulate metal oxide soot. After capture, this soot can be consolidated by sintering to form e.g. clear glass of a purity suitable for drawing into glass optical waveguide fiber.
