Composition alumina ceramics with fibrous components

The interaction of oxides in the Al ₂ O ₃ - ZrO ₂ - MgO system has been studied in the preparation of ceramics using fibrous components. It was found that during the heat treatment of ternary systems, the component that stabilizes the tetragonal structure of zirconium dioxide interacts with the aluminum oxide matrix, forming spinel interlayers at the fiber-matrix phase boundary. The use of highly dispersed fibers as a starting component for the production of ceramics, as well as the addition of a fibrous filler to the gel-like matrix, makes it possible to obtain composite ceramics with increased strength.
