Mechanophysical Methods for Producing Optical Nanoceramics Based on Magnetic Semiconductors

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 these methods are the simplicity of implementation, a combination of nano-grinding and compaction of 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 absorbers and iron-yttrium garnet nanoceramics as an optical element in electromagnetic radiation modulators.
