A glass tube for pharmaceutical containers and a manufacturing process for a glass tube are provided. The glass tubes are characterized by a homogenous and low alkali leachability on the inner surface.

Glass tube for pharmaceutical containers and manufacturing process for a glass tube

A method for producing a glass article having high hydrolytic resistance is provided. A glass tube consisting of borosilicate glass and having an AlOcontent of less than 1 weight-%, a ZrOcontent of 2-12 weight-%, and a glass transition temperature Tis reshaped into a glass article and is subsequently subjected to a thermal post-treatment. To reduce the alkali release of the glass article, the glass article is subjected to a treatment temperature of T&#x2265;T+5&#xb0; K over a treatment time of t&#x2265;5 min and is subsequently cooled during the thermal post-treatment.

Method for producing a glass article

A conversion material for a white or colored light source is provided. The material includes a matrix glass that, as bulk material, for a thickness of about 1 mm, has a pure transmission of greater than 80% in the wavelength region from 350 to 800 nm and in the region in which the primary light source emits light, wherein the sum of transmission and reflection of the sintered matrix glass without luminophore is at least greater than 80% in the spectral region from 350 nm to 800 nm and in the spectral region in which the primary light source emits light.

Conversion material for white or colored light source, method of production, and light source having the conversion material

A pharmaceutical packaging is provided including a glass, comprising at least the following components (given in mol % on oxide basis): SiO: 5 9-84, AlO: 7-18.5, CaO: 1-25, SrO: 0-6.5, BaO: 0-5, ZrO: 0-3, TiO: 0-5, BO: 0-1, wherein the ratio (CaO+SrO+BaO)/AlO&#x3c;2.8, wherein the ratio (CaO+SrO+BaO)/SiO&#x2264;0.39, wherein the hydrolytic resistance according to DIN ISO 720 is class HGA 1, and wherein the glass, apart from unavoidable contaminations, is free of alkali oxides and magnesium oxides.

Pharmaceutical packaging comprising a chemically resistant glass

The invention relates to a conversion material, in particular for a white or colored light source comprising a semiconductor light source as primary light source, comprising a matrix glass that, as bulk material, for a thickness d of about 1 mm, has a pure transmission &#x3c4;of greater than 80% in the wavelength region from 350 to 800 nm and in the region in which the primary light source emits light, wherein the sum of transmission and reflection of the sintered matrix glass without luminophore is at least greater than 80% in the spectral region from 350 nm to 800 nm and in the spectral region in which the primary light source emits light.

Conversion material, particularly for a white or colored light souce comprising a semiconductor light source, a method for the production thereof, as well as a light source comprising said conversion material

An optical converter for producing colored or white light from blue excitation light is provided. The converter has good scattering properties to be able to produce nearly white light from the scattered blue light components and the scattered, converted yellow light components. The optical converter includes material including one or more of a YAG ceramic, a LuAG ceramic, and a magnesium-aluminum ceramic exhibiting strong scattering.

Optical converter for high luminances

Borosilicate glasses, preferably for use in the pharmaceutical sector, are provided. The borosilicate glasses are outstandingly suitable for the use as pharmaceutical primary packaging, such as phials or ampoules, since the aqueous or water-containing medicaments kept in the containers do not attack the glass significantly, and so the glass releases no, or only few, ions. The borosilicate glasses have the following composition in % by weight or consist thereof: 

Borosilicate glass having improved hydrolytic resistance for preferred use in the pharmaceutical sector

The invention relates to luminous substances which contain Eudoping and at least one silicate mineral from the garnet group and/or a mono and/or polycrystalline yttrium-aluminum garnet (YAG) and/or a luminous substance derived from YAlOby partial or complete substitution, and to the production and use thereof.

Luminous substances based on EU2+-(co-)doped mixed garnet crystals and production and use thereof

This invention relates to a flat float glass that can be prestressed or transformed into a glass ceramic with high quartz mixed crystals or keatite mixed crystals. To eliminate undesirable surface defects during floating and to achieve superior characteristics of the glass or of the glass ceramic, in particular with regard to a low coefficient of thermal expansion and high light transmittance, the glass has a concentration of less than 300 ppb Pt, less than 30 ppb Rh, less than 1.5 wt. % ZnO and less than 1 wt. % SnO, and is refined during melting without the use of the conventional fining agents arsenic oxide and/or antimony oxide.

The cooking unit has a glass-ceramic panel () providing a cooking surface, which is made of transparent colorless glass-ceramic bulk material or a glass panel made of pre-stressed transparent colorless glass material. Radiant heating elements () are provided under the glass or glass-ceramic panel, which heat respective cooking zones. The glass or glass-ceramic panel has a full surface decorative coating () on its upper side, which makes dirt and usage marks less conspicuous, and an IR permeable coating () having a solid or plain color, preferably bisque-like, on its underside. The IR permeable coating having the solid or plain color prevents an observer from viewing the internal components of the cooking unit that are under the cooking panel from above it.
