摘要： Disclosed is a thermal insulation to be inserted between two structures, surfaces, walls or the walls of components which are to be insulated. The thermal insulation consists of an plurality of hollow spheres made up by loose hollow spheres or by hollow spheres which are interconnected by sintered contacts. The ratio of the outer diameter of the hollow spheres to their wall thickness is 5 300. The hollow spheres are made of silicides, silicide composites, metals and intermetals and the alloys thereof, ceramics or glass. When the walls of the hollow spheres have a closed porous structure, the inner pressure in the hollow spheres is between 0 to 0.1 that of the surrounding air pressure at room temperature.

摘要： Production of high density intermetallic phase-based materials and components is carried out using a composite powder of the base component in elemental or pre-alloyed form and a second component (preferably aluminium) in elemental or pre-alloyed form, in which one component completely and uniformly encloses the other component and in which each powder particle has a component ratio corresponding to the desired final composition (intermetallic phase), so that no expansion of the consolidated material occurs during sintering. Also claimed is a second similar process in which the second component is a soft metallic/elemental powder, the process comprising (a) mixing the individual powders in a stoichiometric ratio such that the base component powder particles are enclosed by the soft powder particles; and (b) compacting the powder mixture to a component or body, shaping with a deformation ratio of about 20 and machining the body transverse to the shaping direction to produce material or powder which is subjected to uniaxial pressing and pressure-less sintering.

摘要： Die Erfindung betrifft eine Sinterunterlage, die beim Sintern zwischen einem zu sinternden grünfesten Formkörper und einem Grundkörper angeordnet ist. Die erfindungsgemäße Sinterunterlage ist beim Sintern zwischen einem zu sinternden grünfesten Formkörper und einem Grundkörper angeordnet. Sie ist als grünfeste mehrschichtige Folie oder mit einer auf einem metallischen oder keramischen Träger angeordneten grünfesten Folie_ ausgebildet. Außerdem ist eine zwischen dem grünfesten Formkörper (V) angeordnete Trennschicht (IV), die aus einem Werkstoff besteht, der nicht mit dem Werkstoff des grünfesten Formkörpers (V) chemisch und/oder metallurgisch reagiert und während des Sinterns keine stoffschlüssige Verbindung mit dem grünfesten Formkörper (V) eingeht. Die unterhalb der Trennschicht (IV) angeordnete Folienschicht (III) ist mit dem gleichen pulverförmigen Werkstoffgebildet, aus dem der Formkörper hergestellt ist. Es besteht auch die Möglichkeit die Folienschicht (III) aus keramischen oder metallischen pulverförmigem Werkstoff herzustellen oder einen pulverförmigen Werkstoff einzusetzen, der eine chemische Verbindung enthält oder daraus gebildet ist, die während des Sinterns ihr Volumen reduziert.
