In the course of the work were carried out: thermal analysis, including thermogravimetric studies and differential scanning calorimetry, x-ray and high-temperature in situ x-ray studies, the study of the properties and morphology of the composites. The study studied the phase composition and morphology of the initial powders Al2O3 and ZrW2O7(OH)2β€’2H2O. The phase transformations of the mixture under study were determined by heating. By hot pressing the composite material Al2O3 – ZrW2O8 is obtained. It is shown that changes in the parameters of hot pressing leads to a qualitative change in the composition of ceramic composites
