Abstract:
PROBLEM TO BE SOLVED: To obtain a system which is insensitive for a temp. change by sticking an optical member with a fused seal to a base body having almost zero or a negative coefft. of thermal expansion CTE to constitute an optical device and preparing the seal by adding and fusing a low melting point glass frit having a positive CTE and a glass ceramic material having a negative CTE in a mill. SOLUTION: A frit of low melting point glass having a positive coefft. of thermal expansion CTE is blended with a glass ceramic material having a positive CTE in a mill to prepare a sealing paste. The obtd. paste is applied on the surface of a base body 22, on which an optical member 26 is arranged. The paste is heated to the temp. to form a seal during the seal is formed between the member 26 and the base body 22. The base body 22 is preferably β-eucryptite, and at least most of the glass ceramic material added in a mill is a pyrophosphate glass ceramic material having a negative CTE.

Abstract:
PROBLEM TO BE SOLVED: To provide birefringent glass for producing a zero-order half-wave plate from drawn glass less than 2 mm in thickness at 1,550 nm. SOLUTION: A glass batch has a base composition of R 2 O-Al 2 O 3 -B 2 O 3 -SiO 2 wherein R 2 O represents an alkali metal oxide, and contains silver, chloride, and bromine. The glass batch in which silver of at least 0.25 mass%, and chloride and bromine of at least 0.2 mass% in total are present is melted. A silver halide phase is deposited in the glass in an amount constituting a volume fraction of at least 0.001. By applying a stress to the glass, particles of the silver halide are drawn in the glass. The process of depositing the silver halide phase comprises a process of rapidly cooling the melted glass and a process of reheating the same. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
The glass containers described herein have at least two performance attributes selected from resistance to delamination, improved strength, and increased damage resistance. In one embodiment, a glass container may include a body having an inner surface, an outer surface and a wall thickness extending between the outer surface and the inner surface. At least the inner surface of the body may have a delamination factor less than or equal to 10. A tenacious inorganic coating may be positioned around at least a portion of the outer surface of the body. The outer surface of the body with the tenacious inorganic coating may have a coefficient of friction less than or equal to 0.7.
Abstract:
An antimony-free glass comprising TeO2 and/or Bi2O3 suitable for use in a frit for producing a hermetically sealed glass package is described. The hermetically sealed glass package, such as an OLED display device, is manufactured by providing a first glass substrate plate and a second glass substrate plate and depositing the antimony-free frit onto the first substrate plate. OLEDs may be deposited on the second glass substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first glass substrate plate to the second glass substrate plate and also protects the OLEDs disposed therein. The antimony-free glass has excellent aqueous durability, good flow, and low glass transition temperature.
Abstract:
Alkaline earth alumino-silicate glass compositions with improved chemical and mechanical durability and pharmaceutical packages comprising the same are disclosed herein. In one embodiments, a glass composition includes from about 67 mol.% to about 75 mol.% SiO2; from about 6 mol.% to about 10 mol.% Alphal2O3; from about 5 mol.% to about 12 mol.% alkali oxide; and from about 9 mol.% to about 15 mol.% of alkaline earth oxide. The alkali oxide comprises at least Nua2O and K2O. The glass composition is free from boron and compounds of boron and is susceptible to ion exchange thereby facilitating chemically strengthening the glass to improve the mechanical durability.
