Description

This dataset contains images of structure of ceramic samples of solid solutions SS Li0.12Na0.88TayNb1-yO3 with y= 0.05, 0.25, 0.4, 1. Ceramic samples were obtained due to conventional ceramic technology. After that they were extra-fast hardened by the following method. Extra-fast hardening was carried out by the “hammer and anvil” method. An LNTN sample in the shape of a pellet was placed in the middle of a focal spot ~ 10-12 in diameter in a radiant energy concentrator in air atmosphere. The sample lays on the surface of an “anvil”: a copper plate that is cooled by running water. The sample melt obtained at temperatures up to 3500K was strongly hit by a “hammer”. As a result the melt spread out in a thin layer (film) between two cold surfaces with high degree of heat transfer. The images of initial ceramic samples were obtained on scanning electron microscope SEM LEO 42. The images of super-fast hardened samples were obtained by light microscope Axio Observer.
