Abstract An influence of hyper-hardening on structure and mechanical properties of ceramic solid solutions (SS) Li0.12Na0.88TayNb1–yO3 with tantalum concentrations у = 0.05; 0.25; 0.4 has been revealed. The researched was carried out using X-ray diffraction and scanning probe microscopy methods. Two ferroelectric phases co-exist in initial non-hardened SS Li0.12Na0.88TayNb1–yO3: hexagonal R3cH and rhombic P21ma. A symmetric rhombic phasePbnm prevails in hardened samples. Hyper-hardening has been established to sufficiently increase micro-hardness and surface strength of SSLi0.12Na0.88TayNb1–yO3ceramic samples.
