摘要:
In the method according to the invention cold or unheated hardened glass and/or glass-ceramic parts are bonded together with a metallic ductile joining material, preferably silver, copper, aluminum or an alloy of those metals, to form a brittle article. The parts to be joined in an initial unheated state are placed with the metallic ductile joining material between them in a high frequency alternating field with frequencies preferably from 100 to 500 kHz. Then the joining material is inductively heated locally to melt it by means of the alternating field and the parts are pressed together to form a sufficiently strong bond between the parts.

The wok is made from hardened glass or glass-ceramic material so that it has a cooking surface that is easier to clean than prior art metal woks. Furthermore when it is heated a better temperature distribution for cooking is produced and it can be universally heated, either by a radiantly heated body or an atmospheric gas burner. The method of making the wok starts with a glass blank or piece of borosilicate glass, which is heated until it softens and then is shaped or formed into the shape of the wok, optionally ceramicized and cooled.
摘要:
Transparent or transparent dyed lithium aluminium silicate (LAS) glass ceramic material is provided that has an adapted thermal expansion. The material includes high-quartz mixed crystals as the predominant crystalline phase, and a thermal expansion between room temperature and 700° C. from 1.0 to 2.5·10−6/K.
摘要:
A cooking device with a curved-shaped bowl having an inner surface that surrounds a cooking space. To allow such a cooking device to be used in a user-friendly way, the bowl is of a hard glass or a glass ceramic, and the bowl bears an edge that surrounds in a region of a bowl edge.
摘要:
A glass-ceramic cooktop is provided that is made of glass-ceramic material with a flat upper side and an underside. The glass-ceramic material has transmittance values of greater than 0.1% in the visible light range in the total wavelength region greater than 420 nm, a light transmittance in the visible range of 0.8-2.5%, and a transmittance of 0-85% in the infrared at 1600 nm, and wherein the glass-ceramic material has high quartz mixed crystals as the prevalent crystal phase. The underside is flat, unstructured, and coplanar with the upper side.
摘要:
A method for making glass ceramic composite structures, wherein a first and at least a second glass component, with an intermediate layer of a joining solder consisting of glass placed between them, are assembled to form a raw composite structure, wherein the joining solder has a radiation absorption capacity higher than the components to be joined, and wherein the raw composite structure is irradiated with energy, for example IR energy, at least in the area of the joining solder until the joining solder has softened sufficiently to bond together the components and the joining solder to produce a composite glassy structure. Thereafter a ceramization treatment is performed.
摘要:
A glass ceramic as cooktop for induction heating having improved colored display capability and heat shielding is provided. The cooktop includes a transparent, dyed glass ceramic plate having high-quartz mixed crystals as a predominant crystal phase. The glass ceramic contains none of the chemical refining agents arsenic oxide and/or antimony oxide and has a transmittance values greater than 0.4% at at least one wavelength in the blue spectrum between 380 and 500 nm, a transmittance >2% at 630 nm, a transmittance of less than 45% at 1600 nm, and a light transmittance of less than 2.5% in the visible spectrum.
摘要:
A kitchen appliance with a work surface made of a temperature-resistant plastic material or composite plastic material, which has a cooktop receptacle. To reduce the installation effort for use in a row of kitchen appliances, a kitchen sink has cutouts for associated plumbing fixtures and a control panel receptacle is embodied in the work surface, besides the cooktop receptacle. Splash guard edges with support receptacles for support elements for kitchen utensils, kitchen utensil deposits and/or kitchen utensil supports are formed on the work surface.
摘要:
A display device in particular for cooktops is provide that has a glass ceramic with a front side and a back side and a lamp arranged in the area of the back side. The display device further includes an optical compensation filter arranged between the front side and the lamp so as to implement any color impressions easily and inexpensively and in a preselectable manner.
