High-temperature mass spectrometric study and modeling of ceramics based on the Al O -SiO -ZrO system.

Rationale: Materials based on the Al O -SiO -ZrO system are promising for a wide range of high-temperature technological applications, such as thermal barrier coatings in the aviation and space industry or advanced materials in nuclear power reactors. Experimental studies of the ceramics based on this system by the Knudsen effusion mass spectrometric (KEMS) method are of significant interest in designing technological processes for the synthesis and exploitation of the Al O -SiO -ZrO materials.

Methods: Samples of ceramics in the Al O -SiO -ZrO system, including the Al O -ZrO and SiO -ZrO binaries, were prepared by solid-state synthesis.
