Abstract: The present invention provides an amorphous caesium aluminum fluoride complex, a process for its production and the use of the complex as a flux, in particular for the soft soldering of aluminum.

Abstract: Provided is a mat device to be arranged in a basket of a dishwashing machine. The mat device includes a base structure including a rigid supporting structure and a flexible structure allowing the base structure to be at least partially conformed to a bottom of the basket. The base structure is at least partially covered by an elastic material, supports a flexible structure for receiving dishes or cutlery, or is at least partially covered by the elastic material and supports the flexible structure for receiving the dishes or cutlery.

Abstract: The invention relates to a flexible mat device adapted to be arranged on or in a basket (17) of a dishwashing machine. According to the invention, the flexible mat device (1) has an at least partially flexible base structure (3), the base structure being adapted to be bent.

Abstract: The process for preparing a cesium and rubidium salt-containing solution includes a hydrothermal digestion of an uncalcined pollucite and/or calcined lepidolite particulate having an average particle size up to 0.5 mm with an aqueous solution of Ca(OH).sub.2 in a suspension with a mole ratio of SiO.sub.2 to CaO of from 1:2.5 to 1:1.25 in a rotary tubular autoclave at a digestion temperature of 200 to 280.degree. C., under a pressure of from 15 to 65 bar and at a suspension density between 8 and 18% by weight for from 0.

Abstract: This invention relates to the preparation of cesium salts from cesium-aluminum-alum in a process in which the cesium-aluminum-alum is reacted in a single vessel in the presence of water with calcium hydroxide in an amount which is equimolar to the amount of aluminum and with a readily water-soluble calcium salt in an amount which is equimolar to the amount of cesium and the precipitated aluminum hydroxide and the precipitated calcium sulfate are separated by filtration or centrifugation.

Abstract: The method of making a high density saline cesium and rubidium solution includes comminuting uncalcined pollucite and/or calcined lepidolite to a grain size of less than 0.1 mm; combining the comminuted material in the presence of water with Ca(OH).sub.2 at a mol ratio of SiO.sub.2 to CaO of not less than 1:2; hydro-thermally decomposing at a temperature of 200.degree. to 280.degree. C.

Abstract: A process for the production of highly pure alkyl and arylphosphines for gas phase epitaxy processes through the reduction of alkyl and arylphosphinic acid or alkyl and arylphosphonic acid derivatives, with substituted alkali metal aluminum hydrides in a high-boiling solvent such as 1-methylnaphthalin.

Abstract: Organic metallic compounds in the form of phenylarsines are used in epitaxy processes, such as MO-VPE. MO-CVD or MOMBE processes, as well as for ion implantation or the in-situ doping of polysilicon for semi-conductors.
