摘要:
The invention relates to a ceramic substrate material having a first layer having a cavity structure formed therein, and at least one sealing layer situated on at least a part of the cavity structure. The first layer comprises at least one first component made of a crystalline ceramic material and/or a glass material as a matrix, the first layer containing a second component made of a further crystalline ceramic material, with selected mantle areas of the crystals and/or crystal agglomerates of the second component being etched out in such a way that the cavity structure is provided (preferably in the form of a pore and/or tube structure). The sealing layer seals the surface of the first layer in the areas on which it is situated (e.g., above the cavity structure), allowing application of thin-film structures to the cavity structure.

摘要:
A method for producing a ceramic substrate material having a first layer and possibly a further layer is specified. The first layer comprises at least one first component made of a crystalline ceramic material and/or a glass material as a matrix and a second component made of a further crystalline ceramic material, which is provided in the matrix. An etching step is performed, mantle areas of the crystals and/or crystal agglomerates of the second component being etched selectively in the first layer to generate a cavity structure in the first layer. The present invention also relates to a corresponding ceramic substrate material, an antenna or an antenna array, and the use of the ceramic substrate material for an antenna or an antenna array.

摘要:
The invention relates to a microreactor having a substrate (10, 20, 80) with at least one catalytically active material arranged in and/or on a cavity structure (14, 24, 84). The substrate (10, 20, 80) has a first layer (11, 21, 80) and optionally at least one additional layer (12, 22) of a ceramic material, with the first layer (11, 21, 80) being formed from a first component of a crystalline ceramic material and/or a glass material as the matrix and a second component of an additional crystalline ceramic material. The surface areas of the crystals and/or crystal agglomerates of the second component in the first layer (11, 21, 80) are etched out in at least some areas to form the cavity structure (14, 24, 84).
