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.

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&#x2013;80), quality (800&#x2013;5000) and Tkf (&#xb1;20 ppm/K) to be specifically predetermined. The glass ceramic mass is characterised by a densification temperature of under 910&#xb0; C. and can is therefore suitable for use in LTCC (low temperature cofired ceramics) technology, for integrating a passive electrical component in the volume of a multilayered ceramic body. Silver in particular can be used as an electroconductive material in this case.

Glass ceramic mass and use thereof

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.

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.

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.
