Abstract
This paper considers mechanophysical methods (shear under pressure and explosive loading) developed for producing high-density optical nanoceramics based on some oxide magnetic semiconductors and their optical properties. Advantages of the techniques are the ease of implementation, a combination nano grinding and compaction of the material in a single process, obtaining high-density (99 %) stable materials, and the absence of external impurity. It is shown that copper oxide nanoceramics can be used as solar energy absorber and iron-yttrium garnet nanoceramics as an optical element in electromagnetic radiation modulators.
