CERAMIC COMPOSITE MATRICES BASED ON THE HfSiO4-ZrO2 SYSTEM
The results of the synthesis of precursor powders, by sintering of which (1 ‒ х)HfSiO4 – хZrO2 ceramic composites are obtained, are presented. Thermal behavior of precursor powders has been studied. It was shown by X-ray diffraction that the addition of ZrO2 promotes the crystallization of HfSiO4, and zirconium oxide in the compositions is X-ray amorphous. The Vickers microhardness values are determined and photographs of the fracture surface of ceramic samples are presented.
