Abstract
- The study investigates alterations in the mechanical and thermophysical properties of ceramics composed of xLi<subscript>2</subscript>ZrO<subscript>3</subscript>–(1−x)Li<subscript>4</subscript>SiO<subscript>4</subscript> as radiation damage accumulates, mainly linked to helium agglomeration in the surface layer. This research is motivated by the potential to develop lithium-containing ceramics characterized by exceptional strength properties and a resistance to the accumulation of radiation damage and ensuing deformation distortions in the near-surface layer. The study of the radiation damage accumulation processes in the near-surface layer was conducted through intense irradiation of ceramics using He<superscript>2+</superscript> ions at a temperature of 700 °C, simulating conditions closely resembling operation conditions. Following this, a correlation between the accumulation of structural modifications (value of atomic displacements) and variations in strength and thermophysical characteristics was established. During the research, it was observed that two-component ceramics exhibit significantly greater resistance to external influences and damage accumulation related to radiation exposure compared to their single-component counterparts. Furthermore, the composition that provides the highest resistance to softening in two-component ceramics is an equal ratio of the components of 0.5Li<subscript>2</subscript>ZrO<subscript>3</subscript>–0.5Li<subscript>4</subscript>SiO<subscript>4</subscript> ceramics.
