Ceramic material with layered structure
The invention provides a ceramic material with a layered structure, and belongs to the field of ceramic materials. Comprising a ceramic layer and an interface layer which are stacked. The adjacent ceramic layers are discontinuously combined through the interface layers, high-speed impact energy forms pressure stress on the impacted surface of the ceramic, and the laminated ceramic structure is combined with a weak interface (a weak combination interface is formed between the ceramic layers after co-sintering), so that impact waves can be effectively blocked and dispersed, damage caused by concentration of the impact waves is prevented, and the service life of the laminated ceramic structure is prolonged. The quality protection capability is improved, the ceramic layer comprises a titanium iron bismuth cobaltate ceramic material, cobalt ions are used for replacing part of iron ions, the Bi7Fe3-xCoxTi3O21 layered Aurivillius multiferroic oxide ceramic is obtained, and the ferroelectricity and ferromagnetism of the ceramic material can be improved. The data of the embodiment shows that the ceramic material provided by the invention has both ferromagnetism and impact resistance.
本发明提供了一种层状结构的陶瓷材料，属于陶瓷材料领域。包括层叠设置的陶瓷层和界面层。本发明通过界面层使相邻陶瓷层之间不连续地结合，高速冲击能量在陶瓷受冲击面形成压应力，本发明通过叠层陶瓷结构与弱界面(共烧结后的各陶瓷层之间形成弱结合界面)结合，可以有效阻隔、分散冲击波，防止冲击波集中造成的破坏，提高质量防护能力，且本发明的陶瓷层包括钛铁钴酸铋陶瓷材料，以钴离子代替部分铁离子，得到Bi7Fe3‑xCoxTi3O21层状Aurivillius型多铁氧化物陶瓷，能够改善陶瓷材料的铁电性和铁磁性。实施例的数据表明，本发明提供的陶瓷材料兼顾铁磁性和抗冲击性能。
