Structure of hyper-hardened solid solutions Li0.12Na0.88TayNb1-yO3

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.

本数据集收录了具有不同y值（0.05、0.25、0.4、1）的固态溶液SS Li0.12Na0.88TayNb1-yO3的陶瓷样品结构图像。陶瓷样品通过传统陶瓷技术制备而成。随后，采用以下方法进行超快速硬化处理。超快速硬化通过‘锤砧’法进行。将形状为药丸的LNTN样品置于辐射能量聚集中器焦点区域直径约为10-12英寸的中央位置，该聚集中器置于空气环境中。样品放置在‘砧面’上：一个通过流水冷却的铜板。在高达3500K的温度下获得的样品熔融物被‘锤子’猛烈撞击，从而在两个具有高传热效率的冷表面之间形成一层薄薄的熔融膜。初始陶瓷样品的图像通过扫描电子显微镜SEM LEO 42获取，而超快速硬化样品的图像则通过光学显微镜Axio Observer获取。
