Abstract
Ceramic composites (1 ‒ x)ZrSiO4‒xZrO2 with low thermal conductivity were obtained by sintering nanosized powders in the range of 1000‒1300 °C in air. The fracture surface of ceramic samples after sintering at 1300 °C was investigated and their thermal behavior was studied by dilatometry. The chemical resistance of composites by leaching in distilled water was evaluated. In the future, such ceramic composites can be used as matrices for the purpose of long-term, environmentally safe storage and subsequent final isolation from the environment of individual isotopes of actinide-rare earth fraction of high-level waste (HLW).
