摘要： Novel cellular solids and foams from amorphous materials with a glass transition temperature (Tg) and methods of forming such materials are provided. In particular, foams are formed by expanding or compressing hollow spheres made of a high strength amorphous material, which is defined as a material having high strength characteristics, but also possessing a glass transition within a confined space. Using such a method, it has been unexpectedly found that it is possible to make cellular structures, including both open and closed cell foams, with customizable properties from materials that have been inaccessible with conventional methods. Moreover, based on calculations high specific strengths and stiffnesses are expected.

摘要： The production of quartz glass granules comprises the granulation of pyrogenically produced silicic acid and the formation of a SiO2 granulate (9), the drying and cleaning of the SiO2 granulate (9) by heating in an atmosphere containing halogen, and the vitrification of the SiO2 granulate (9) under a treatment gas which contains at least 30% by volume of helium and/or hydrogen. This process is time-consuming and expensive. In order to provide a method which, starting from a porous SiO2 granulate (9), allows the cost-effective production of dense, synthetic quartz glass granules suitable for melting bubble-free components of quartz glass, the invention proposes that the cleaning and vitrification of the SiO2 granulate (9) and a post-treatment of the vitrified quartz glass granules are carried out in each case in a rotary tube (6) of a rotary kiln (1), said rotary tube rotating about a central axis (7), wherein the rotary tube (6) comprises an inner wall made of a ceramic material during vitrification, and wherein the vitrified quartz glass granules are subjected to a post-treatment during a treatment period of at least 10 minutes in an atmosphere which contains less than 20% of helium or hydrogen at a treatment temperature of 300° C. or more.

摘要： Hollow microspheres produced by the present method each have a hollow interior evacuated of gases to a predetermined pressure. A reflective material layer coats the exterior of each microsphere and, optionally, an outer layer of a protective material is applied over the reflective material layer. Permeant gases are dissolved into glass or plastic frit particles prior to heating of the frit particles to form hollow microspheres having the permeant gases contained therein. The permeant gases are subsequently out-permeated in a non-permeant gas atmosphere to substantially evacuate the interior of each microsphere. The exterior layers of reflective material and protective material are then coated about each evacuated microsphere.

摘要： A method is provided for the production of low density, internally coated, evacuated microspheres wherein the sphere density is uniform and the sphere diameter and wall thickness can be controlled accurately. In a preferred embodiment of the instant method, molten glass (or other suitable nonmetallic material) is used to encapsulate zinc or another suitable metal in either the solid or liquid state. After the metal has been encapsulated the temperature of the particle is increased until the encapsulated metal vaporizes and blows the particles into thin-walled, hollow spheres which are then quenched so that the encapsulating walls become rigid before the condensing metal vapor on the inside of the walls causes the spheres to collapse.
