Abstract
A comparative study of thermal transformations of ceramic mass (CM) based on α-Al2O3 modified with vanadium oxide additives introduced into CM by wet mixing and by deposition on the surface of the CM particles using molecular layering nanotechnology was carried out. The structural and chemical transformations of the obtained compositions were characterized by differential thermal analysis under linear heating conditions at a rate of 10°С/min, in the temperature range from room temperature to 1000°C. Changes in the phase composition, specific surface area of the compositions, and the state of the modifying additive before and after heating were studied using x-ray diffraction, low-temperature nitrogen adsorption, and ultraviolet–visible diffuse reflectance spectroscopy
