Preparation method of multilayer composite structured transparent ceramic
The invention relates to a preparation method of multilayer composite structured transparent ceramic, which is characterized in that the prepared multilayer ceramic meets a structure shown in the following formula: YAG/Re: YAG/YAG; a middle layer is Re:YAG multilayer consisting of a (Y1-xRex)3Al5O12 component flake, and two end layers are respectively a YAG multilayer consisting of a Y3Al5O12 flake. The method comprises the following steps: preparing a size for flow casting; then, carrying out tape casting, and sintering the obtained object so as to obtain a multiple YAG/Re: YAG/YAG composite structured ceramic biscuit; and finally, calcinating the biscuit in the air, and then sintering the obtained product in a vacuum environment, so that the multilayer composite structured transparent ceramic is obtained. The multilayer composite structured transparent ceramic prepared according to the invention has the characteristics of high purity, complicated structure, good optical quality, high transmittance, small ion diffusion scope, and the like, and is extremely applicable to the preparation of large-sized and complex-structured YAG-based transparent ceramic materials.
