The invention pertains to a method for manufacturing a formed body with a cavity structure for the sound and/or heat insulation of buildings. According to the invention, pre-foamed polystyrene particles are compressed into a formed body in a mold or on a conveyor belt system under the influence of heat and/or pressure, wherein the degree of compression amounts to 0.2-0.8, preferably 0.3 to 0.7, particularly 0.4 to 0.6, such that a communicating cavity volume is preserved in the formed body. The invention furthermore pertains to a formed body for the sound and/or heat insulation of buildings.

The invention relates to a process for producing metal foams of controlled structure and to the metal bodies in foam form obtained in this way, wherein metals from group IB to VIIIB of the periodic system of the elements are added before and/or during the formation of the foam.

Production of metal forms

The invention relates to a process for producing metal foam and to a metal body produced using this process. The object is achieved by a process for producing metal foam by adding a blowing agent to a metal melt, wherein the metal melt is introduced into the die cavity of a metal die-casting machine and is foamed using a blowing agent which releases gases and is solid at room temperature.

Process for producing metal foam and metal body produced using this process

The invention relates to a process for producing metal/metal foam composite components, wherein a flat or shaped metal part is introduced into the cavity of a die, the cavity being at least partially delimited by the metal part, and then a mixture comprising a metal melt and a blowing agent which is solid at room temperature is introduced into the cavity, where it is foamed.

The invention relates to a process for producing shaped metal parts, in particular reduced-weight shaped parts made from metallic materials. In this process, a metal body with a surface which is closed on all sides and a hollow structure in the interior is placed into a die as a core and is then surrounded with a metal melt by casting. The surface region of the metal body has a mean density which is higher than the interior of the metal body by a factor of 1.5 to 20.

Use of zinc treated with metal hydride in organometallic synthesis

A process for producing metal foams comprising mixing one or more metal powders, if desired combined with particulate metallic or nonmetallic, e.g., mineral, additives of varying particle size, with a gas-liberating blowing agent; optionally preheating the mixture in an open or closed mold to a temperature below the decomposition temperature of the blowing agent; subsequently heating the mixture to a temperature above the melting point of the lowest-melting metal in such a way that the temperature rises from the equilibrium decomposition temperature of the blowing agent to the melting point of the metal in a time which is shorter than the time required to reach the equilibrium state in the blowing agent/blowing gas system at this temperature and subsequently cooling the resulting metal foam to a temperature below the melting point of the lowest-melting metal is provided as well as foamed metal bodies obtained using the inventive process.

Innovative siloxane block copolymers with rigid spacers and their use

A process for separating molten metals, the molten metals being treated with metal hydrides is provided. The molten metals employed are from Groups II-IV of the Periodic Table of Elements and the subgroups, including their alloys, and are distinguished by the fact that the metals or alloys are reacted with a metal hydride in a molten bath.

The invention relates to activated magnesium metal, to a method of activating magnesium metal and to its use for the preparation of organomagnesium compounds. The activated magnesium metal is obtainable by reacting molten magnesium metal with magnesium hydride; or by heating a mixture of magnesium metal and magnesium hydride until molten.
