Compositions: Ceramic > Ceramic Compositions > Devitrified Glass-ceramics > Nonsilica And Nonsilicate Crystalline Phase (e.g., Spinel, Barium Titanate, Etc.) Nonsilica And Nonsilicate Crystalline Phase (e.g., Spinel, Barium Titanate, Etc.)Nonsilica And Nonsilicate Crystalline Phase (e.g., Spinel, Barium Titanate, Etc.) patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/02/06 - 20060247117 - Method of making polarizing glasses Polarizing glass articles and methods of manufacturing polarizing glass articles are disclosed. The method involves forming a polarizing layer on the surface of the glass article by ion-exchanging silver or copper into the surface. ... 07/27/06 - 20060166804 - Crystallisable glass and the use thereof for producing extremely solid and break resistant glass-ceramics having an easily polished surface The invention relates to crystallisable aluminosilicate magnesium-containing glass which is used for producing extremely solid and break-resistant glass-ceramics having an easily polished surface. The inventive crystallisable glass contains 5-33 mass % of SiO2, 25-40 mass % of Al2O3, 5-25 mass % of MgO, 0-15 mass % of B2O3, 0.1-30 mass ... 06/15/06 - 20060128547 - Composition for ceramic substrate, ceramic substrate, process for producing ceramic substrate and glass composition A ceramic substrate composition is provided which can be co-fired with a low-melting metal and exhibits excellent dielectric characteristics at high frequencies, particularly tens of gigahertz. The ceramic substrate composition mainly contains a glass represented by aB2O3-bRe2O3-cZnO, wherein the molar ratios (a, b, and c) fall within a region defined ... 01/12/06 - 20060009342 - Glass ceramics for laser systems A glass-ceramic material, particularly for elements in laser systems, and a method for preparing same. The glass-ceramic material may be used for an optical fiber for communication systems and laser systems. The glass-ceramic may include gahnite crystals and optionally β-quartz-like solid solution, or a petalite-like crystals, spinel, and zirconia crystals. ... 12/15/05 - 20050277540 - Highly birefringent glass A birefringent glass composed of a phase-separated glass is provided. The phase-separated glass includes a borosilicate glass in which fluorine and a constituent that tends to crystallize into a high refractive index phase as a consequence of phase separation are included. In one embodiment, the constituent comprises TiO2. ... 09/29/05 - 20050215411 - Dielectric ceramic material and multilayer ceramic substrate A dielectric ceramic material which is obtained by firing a raw material comprising an alumina powder and a glass powder containing at least SiO2 and MgO, the dielectric ceramic material being characterized in that a ratio (MgAl2O4 (311)/Al2O3 (116)) in X-ray diffraction peak intensity of an MgAl2O4 (311) to an ... ### FreshPatents.com Support |
