Solid-phase reaction preparation method and doping modification method of zinc manganate ceramic
The invention discloses a solid-phase reaction preparation method and a doping modification method of zinc manganate ceramic, and belongs to the technical field of zinc manganate ceramic preparation and doping modification. The problem that ZnMn2O4 ceramic is difficult to synthesize by an existing solid-phase reaction method is solved. The ZnMn2O4 ceramic is successfully prepared by adopting a two-step sintering method and utilizing a solid-phase reaction, and aiming at the problems that the ZnMn2O4 ceramic is relatively high in loss and cannot be used as a voltage stabilizer for a long time, the ZnMn2O4 ceramic is modified by adopting doping, a local stress field and an electric field formed by doping ions are utilized, and the voltage stabilizer can be used as a voltage stabilizer for a long time. The voltage-sensitive property and the dielectric property of the zinc manganate ceramic are induced to be controllably changed, the non-linear conductivity coefficient of the zinc manganate ceramic is effectively regulated and controlled, a threshold electric field can be regulated and controlled, and the application range of the zinc manganate ceramic is widened.
本发明公开了一种锰酸锌陶瓷的固相反应制备方法及其掺杂改性方法，属于锰酸锌陶瓷制备及其掺杂改性技术领域。本发明解决了现有固相反应法合成ZnMn2O4陶瓷困难的问题。本发明采用两步烧结法利用固相反应成功制备了ZnMn2O4陶瓷，并针对ZnMn2O4陶瓷的损耗较高，无法长时间作为稳压器件使用的问题，采用掺杂对锰酸锌陶瓷进行改性，利用掺杂离子形成的局部应力场和电场，诱导锰酸锌陶瓷压敏性能和介电性能的可控变化，实现对锰酸锌陶瓷电导非线性系数的有效调控，并且阈值电场可调控，拓宽了锰酸锌陶瓷的应用范围。
