As a result of the combination of the processes of selfpropagating high-temperature synthesis (SHS) and shear high-temperature deformation, realized in the method of SHS-extrusion, ceramic rods based on Al2O3‒SiC‒TiB2 were obtained. The influence of technological parameters of the process (delay time, pressing pressure) on the length of the obtained rods has been studied. The obtained materials were annealed in the range 1000‒1300 °C, and the microstructure and phase composition of the materials were studied before and after heat treatment.

The physical, chemical and structural developments taking place in the aluminum-phosphate composites when heating under the load were investigated in the article. The X-Ray diffraction analysis, the electronicoptical and scanning microscopy with embedded energy-dispersive spectral measurement system were used to study both the compositions of the resulting products after the α-Al2O3‒phosphate binder composite's hardening and the transformations of these products in the high-temperature interaction regions. The investigating results allowed to predict the ceramics' deformation behavior in service and to optimize the production technique for the refractory ceramic materials with the tailored characteristics.Ill.8.
