Abstract: A clothes dryer includes at least one clothes drum for receiving textiles and at least one ultrasound atomizer disposed in the dryer for generating an aerosol from a liquid. The invention further relates to a method for introducing an aerosol into the clothes drum of the clothes dryer. A liquid is conducted from a reservoir to an ultrasound atomizer disposed in the clothes dryer, atomized there, and conducted into the clothes drum. The invention relates to further applications for an ultrasound atomizer, such as a washing machine, dishwasher, and/or motor vehicle.

Abstract: The invention relates to a glass ceramic mass containing at least one oxide ceramic containing barium, titanium and at least one rare earth metal Rek; and at least one glass material containing at least one oxide with boron, at least one oxide with silicon and at least one oxide with at least one bivalent metal Me2+. The glass ceramic mass is characterised in that the glass material contains at least one oxide with bismuth, especially bismuth trioxide. The oxide ceramic is especially a microwave ceramic of formula BaRek2Ti4O12, Rek being neodymium or samarium. The composition of the oxide ceramic remains essentially constant during the sintering of the glass ceramic, enabling the material properties of the glass ceramic mass, such as permittivity (20–80), quality (800–5000) and Tkf (±20 ppm/K) to be specifically predetermined. The glass ceramic mass is characterised by a densification temperature of under 910° C.

Abstract: A ceramic mass includes one ceramic material and at least a second different ceramic material. Glass material is arranged between the ceramic materials. The glass material reduces the sintering temperature of the ceramic mass and prevents the various ceramic materials from forming a mixed crystal when the ceramic mass is sintered. The ceramic mass is suitable for use in LTCC technology for the production of capacitors whose permittivity is dependent upon a specific temperature range.

Abstract: A method for introducing at least one gaseous reducing agent for a nitrogen oxide into a gas mixture, and a device for carrying out the method. Thermal energy is supplied to a body made from a starting material of the reducing agent, so as to form the reducing agent. The starting material used is urea. The reducing agent formed is ammonia. This method is used in particular to reduce nitrogen oxides in the exhaust gas from internal-combustion engines.

Abstract: A plastic compound (1) comprises at least one organic starting compound (2) of at least one ceramic material (5), and at least one inorganic starting material (3) of the ceramic material (5), the ceramic compound comprising a glass material (4). By subjecting the plastic compound to pyrolysis an electrically insulating glass ceramic (6) having relatively high mechanical stability is obtained. The plastic compound is used as cable sheathing of a cable core. The cable sheathing allows to preserve the functionality of the cable in the case of a cable fire.

Abstract: The invention relates to a glass ceramic mass, comprising at least one oxide ceramic, containing barium, titanium and at least one rare earth metal Rek and at least one glass material, containing at least one oxide with boron and at least one oxide of a rare earth metal Reg. The glass material further contains either an oxide of a tetravalent metal Me4+, or at least one oxide of a pentavalent metal Me5+. A compression of the glass ceramic mass occurs above all by viscous flow. A low vitrification temperature can thus be achieved. Crystallisation products are produced during and/or after the compression. The rare earth oxide and the crystallisation products can be used to pre-determine each of a dielectric material property of the glass ceramic mass in a wide range such as permittivity (15-80), Q (350-5000) and Tf value (±20 ppm/K). The glass ceramic mass is characterised by a vitrification temperature of below 850° C.

Abstract: In a method for producing a PZT piezoceramic, an intermediate compound is formed having the formula Zr.sub.x Ti.sub.1-x (O.sub.2 (ZTO) in a hydrothermal process. A ceramic having a desired zirconium/titanium ratio can be produced from two such ZTO powders having respectively different x-values. These powders are blended with lead oxide, and if desired with dopants, and are converted into a PZT powder by calcining. The calcined PZT powder is then sintered to form a high-density PZT ceramic which can be aligned precisely at the morphotropic phase boundary.
