Abstract
A technology of perovskite-type Li0.12Na0.88Ta y Nb1 – y O3 ceramic solid solutions based on sodium and lithium niobates and tantalates and a method of their ultrafast quenching have been presented. The influence of quenching on the structure of ceramic samples and the variations in crystallographic and fine structure parameters have been studied. It has been found that ultrafast quenching results in a preferred orientation of crystallites, severe local microstrains, and changes in the atomic structure of Li0.12Na0.88Ta y Nb1 – y O3 ceramics.
