摘要： The invention relates to hollow balls comprising shells consisting of a sintered inorganic material, such as metals, metal oxides or ceramics. The invention also relates to methods for producing lightweight structural elements by means of such hollow balls. The aim of the invention is to enlarge the field of application, to technologically simplify the treatment for producing structural components and to improve the application characteristics of the hollow balls and the structural components produced therewith. An additional solid functional layer is designed on the hollow balls and on a shell. The material of the functional layer can be formed in a free-flowing, plastic and/or elastic manner owing to a physical and/or chemical treatment.

摘要： According to the invention, the shaped bodies are comprised of at least one heavy metal, preferably Fe, Ni, Co, Sn, Mo or W, which can be reduced from a corresponding metal compound at a temperature of less than 1,500 °C. The shaped bodies have an outer diameter ranging from 0.05 to 0.5 mm and a diameter to wall thickness ratio ranging from 0.5 to 3 %. According to the method, starting materials are applied as a covering layer to supporting elements of any shape, and the green products produced in such a manner are subsequently heat-treated. During the heat-treatment, the supporting elements are pyrolyzed, the covering layers are, in essence, thermally decomposed, and the decomposition products are sintered. The outer dimensions of the supporting elements are selected such that they are larger than the shaped bodies to be produced. Metallic compounds, preferably metal oxides, metal hydroxides, metal carbonates, or organometallic compounds are selected as starting materials and can be reduced at a temperature of less than 1,200 °C. The heat treatment is carried out in a reductive atmosphere containing hydrogen and/or carbon in such a way that the starting materials are essentially reduced to the sintered metal which provides the foundation for the respectively used metal compound.
