Patents - CERAMICS AND GLASSES

Category list

January 2007
CERAMICS AND GLASSES
WO 2006/091441 A1 (08/31/06) Guardian Industries Corp.
Longobardo A, Landa L, Landa K.A, Thomsen S.V.
GREY GLASS COMPOSITION
A grey glass composition employing in its colorant portion, iron, cobalt, nickel, and at least one of erbium and titanium. The use of erbium and/or titanium has been found to improve coloration of the grey glass, and improve tunability of the same. The ratio of cobalt oxide to nickel oxide is from 0.22 to 0.30 in order to achieve desired coloration in certain cases.
WO 2006/076155 A2 (07/20/2006) Massachusetts Institute of Technology
Schuh C.A, Detor A.J
PRODUCTION OF METAL GLASS IN BULK FORM
Metal glasses in bulk form eg a tennis racquet head are electroformed from elements that can not be cast using electrodeposition. Such compositions may include: Cobalt and Tungsten; Cobalt and Zinc, plus many others. Metal glass objects may include a core of another material. Electrodeposition liquid may be aqueous, alcohol, hydrogen chloride, or metal salt.

WO2005/105686 A1 (11/10/2005) Koninklijke Philips Electronics N.V.
Flink S., Ulenaers H.M.P., Steinmann M.W.
GLASS COMPOSITION FOR BLUE LAMP BULBS, USE OF SUCH A COMPOSITION FOR FORMING A BULB, AND AUTOMOTIVE LAMP EMITTING BLUE LIGHT AND INCLUDING A SUCH BULB
A blue glass composition for use in lamp bulbs includes cobalt oxide and also contains alkali metal oxide such as lithium oxide. Such a composition has a glass transition temperature Tg below 700C

WO 2005/095295 A1 (10/13/05) Ministry of State for Environm (EG) hassaan Mohamed Yousry Mohamed
Hassaan M.
USE OF BY-PASS DUST OF CEMENT INDUSTRY IN GLASS MANUFACTURE
The by-pass dust from Portland cement manufacture could partially or completely replace sand, which constitutes 10-70% of the total components, in glass manufacture. Other components are broken glass, sodium, potassium, magnesium, barium, arsenic, carbonates and aluminum oxide and soda ash and colouring oxides such the oxides of iron, cobalt and selenium.
WO 2005/077851 A1 (08/28/05) Nippon Sheet Glass Company Limited
Tsuda M.
GLASS COMPOSITION FLUORESCENT IN INFRARED WAVELENGTH REGION AND METHOD FOR AOMPLIFYING SIGNAL LIGHT USING SAME
A glass composition having an improved luminescence intensity, contains bismuth as an emission element and a glass network former and dysprosium, erbium, ytterbium, neodymium, thulium, holmium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper or molybdenum (excluding tetravalent titanium and trivalent iron).
WO 2004/094331 A3 (08/28/05) Corning Incorporated

GLASS COMPOSITION WITH LOW VISIBLE AND IR TRANSMISSION
A2 published (03/04/04)
WO2004/094331 A2 (11/04/04) Corning Incorporated
"Reddy, K. P.; Schroeder, J. F.; Streltsov, A.; Powley, M. L.; Morena, R. M"
HERMETICALLY SEALED GLASS PACKAGE AND METHOD OF FABRICATION
"A hermetically sealed glass package eg OLED display is manufactured by using two substrate plates, the second of which contains a transition metal such as cobalt. A sensitive thin-film device is deposited on the first substrate plate and a laser is then used to heat the doped second substrate plate so that a portion of it swells and form a hermetic seal between the plates thus protecting the thin film device. "
WO2005/005336 A1 (01/20/05) Corning Incorporated
"Beall, D. M.; Beall, G. H."
BETA-SPODUMENE CERAMICS FOR HIGH TEMPERATURE APPLICATIONS
"Beta-spodumene ceramics having low thermal expansion, high porosity and high strength for use in high temperature applications, including emissions control systems, absent a glass component. The ceramics are produced from a solid-solution of beta-spodumene ranging in molar ratio from 1:1:4 LiO2-Al2O3-SiO2 to 1:1:11 LiO2-Al2O3-SiO2 where MgO, MnO or CoO is substituted for lithium oxide (LiO2) at 10 to 65 mole %,"
"WO2005/005320 A1 (01/20/05) Ibule Photonics Co., Ltd."
"Lee, S-G.; Kim, M-C.; Choi, B-J.; Shin, M-C.; Yu, Su-H."
"A FERROELECTRIC CERAMIC COMPOUND, A FERROELECTRIC CERAMIC SINGLE CRYSTAL, AND PREPARATION PROCESSES THEREOF"
"Ferroelectric ceramic compounds having the composition: s[L]-x[P]y[M]z[N]p[T], are relaxor ferroelectrics having desirable properties for manufacturing single crystals for tunable filters. [P] PbO, [M] is MgO or ZnO, [N] is Nb2O5, [T] is TiO2, [L] is lithium tantalate or lithium niobate, lithium, lithium oxide, platinum, indium, palladium, rhodium, nickel, cobalt, iron, strontium etc."
WO2005/009915 A2 (02/03/05) Guardian Industries Corp.
"Thomsen, S. V.; Hulme, R.; Landa, L.; Landa, K. A."
GREY GLASS COMPOSITION
"A grey glass composition employing in its colorant portion at least 0.0001 to 0.05 % iron (expressed as Fe2O3), 0.25 to 0.70 % cerium oxide, 0.0001 to 0.05 % cobalt oxide and 0.01 to 1.0 % selenium allows high visible transmission, and satisfactory IR and UV absorption, while at the same time achieving desired grey color."
WO2005/033030 A1 (04/14/05) Guardian Industries Corp.
"Landa, K. A.; Landa, L.; Hulme, R.; Thomsen, S. V."
CLEAR GLASS COMPOSITION WITH HIGH VISIBLE TRANSMITTANCE
"An oxidizing agent(s) such as cerium oxide (e.g., CeO2) is added to a glass batch in order to significantly lower; the redox of the glass (preferably to <= 0.05) and the ferrous content to 0.0001 to 0.05%. and give a high transmittance fairly clear/neutral colored glass. To compensate for yellow or yellow-green coloration a small amount of cobalt (Co) may be added."
