The influence of the high-temperature deformation on the aluminum-phosphate composites structure

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.
