对于用烧结方法制备的陶瓷超导体来说,烧结体内部显微结构的控制,是获得稳定性能的关键。为此,日本东京工业大学的水谷惟恭撰文介绍了晶粒直径控制、晶界设计等新的陶瓷制造技术他认为:烧结陶瓷的性能是由四个要素决定的,即构成显微结构的晶粒,晶界、气孔和二次相。晶粒直径控制是显微结构控制之一。若改变烧结体的晶粒尺寸,则很多性能会同时发生变化,如磁性,光学性能,热性能
For the ceramic superconductor prepared by the sintering method, the control of the microstructure inside the sintered body is the key to obtain stable performance. To this end, Japan’s Tokyo Institute of Technology, Mizutani Goryeong wrote an introduction to the grain diameter control, grain boundary design and other new ceramic manufacturing technology He believes that the performance of sintered ceramics is determined by the four elements that form the microstructure of the grain , Grain boundaries, pores and secondary phases. Grain diameter control is one of microstructure control. If you change the grain size of the sintered body, many of the properties will change at the same time, such as magnetic, optical properties, thermal properties
