摘要:
An oven muffle having a receiving space, at least some regions of which are delimited by wall elements, in which at least one of the wall elements is permeable to IR radiation or has a region that is permeable to IR radiation. In the oven muffle, the cooking performance is successfully improved while also providing an easily cleanable interior because a reflecting element that reflects IR radiation is positioned in the region of the outer surface of the wall element on a side oriented away from the receiving space.

A method for melting inorganic materials, preferably glasses and glass-ceramics, in a melting unit with cooled walls is provided. The method includes selecting the temperature of at least one region of the melt is selected in such a way as to be in a range from Teff−20% to Teff+20%, where the temperature Teff is given by the temperature at which the energy consumption per unit weight of the material to be melted is at a minimum, with the throughput having been selected in such a way as to be suitably adapted to the required residence time.
摘要:
A lithium-aluminosilicate glass or a corresponding glass ceramic that has a content of 0-0.4SnO2, 1.3-2.7% by weight of ΣSnO2+TiO2, 1.3-2.5% by weight of ZrO2, 3.65-4.3% by weight of ΣZrO2+0.87 (TiO2+SnO2), ≦0.04% by weight of Fe2O3, 50-4000 ppm of Nd2O3 and 0-50 ppm of CoO is described. The glass or the glass ceramic is color-neutral, has a turbidity of less than 1% HAZE and a high light transmission. The glazing time for conversion of the glass into glass ceramic is especially short with less than 2.5 hours.
摘要:
A substrate, such as a glass, glass ceramic, ceramic or metal substrate, is provided with a thermocatalytically active coating on at least a part of the substrate surface. The thermocatalytic coating contains an inorganic lithium salt or organic lithium-containing compound in an amount that is equivalent to not less than 2 wt. % of lithium ions, based on total coating weight. The thermocatalytic coating has a glass, glass solder or sol-gel matrix in which the lithium salt or organic lithium-containing compound is introduced. Optional barrier and IR-reflecting layers are arranged between the substrate surface and the thermocatalytically active coating.
摘要:
The heat reflecting arrangement with an improved high heat resistance, e.g. 100 hours at 500° C., includes a substrate, a heat reflecting layer (A) on at least one side of the substrate, which contains indium tin oxide (ITO), and a barrier layer (B) that covers the heat reflecting layer (A), which contains a metal oxide and/or a metal nitride. A fireplace or baking oven with a viewing window having this layer system with the heat reflecting layer is also described. In addition a process for providing the heat reflecting arrangement is described.

摘要:
An insulating glass element for the at least partial delimitation of a combustion chamber, having at least two viewing panes, which have at least some areas a transparent glass or ceramic-glass material and are arranged spaced apart from each other while leaving an air chamber, and wherein a viewing area is created at least in parts of the air chamber. The two viewing panes are connected with each other by a temperature-resistant adhesive, and the adhesive encloses a viewing area of the viewing panes all around, or a spacing element, which runs around them at least partially, is connected with the two viewing panes in a material-to-material manner, preferably by a glued connection.

摘要:
The invention relates to a method and a device for producing colored glasses. The aim of the invention is to obtain a paricularly intimate mixture and to enable a quick change of the melt at the same time. To this end, the following procedure steps are applied: a melt made of a compound or fragments of glass is produced, the glass melt is further processed in at least one additional vessel, the melt is supplied to a skull device (3) (skull pot or skull channel) during subsequent processing, a dye is supplied (6, 6.1) to the melt after the melt was in the melting station (1) but before the melt enters the skull device (3) or while said melt is in the skull device.
