Preparation method for porous lithium zirconate block
The invention discloses a method for a porous lithium zirconate block. The method comprises the following steps sequentially: (1), dissolving inorganic zirconium salt, inorganic lithium salt, a complexing agent and a phase separation inducer in a solvent, and stirring until a transparent clear solution is obtained; (2), slowly adding a gel accelerator into the transparent clear solution, uniformly stirring, and ultrasonically processing in an ultrasonic instrument until air bubbles in the solution are removed; (3), putting a homogenous solution obtained in the step (2) into a container, sealing, and gelling at 60-90 DEG C for 5-25 minutes to obtain wet gel; (4), ageing the wet gel obtained in the step (3) at 60-90 DEG C for 4-10 hours; (5), drying the aged gel obtained in the step (4) at 20-50 DEG C for 50-100 hours, heating to 650-1,200 DEG C, and performing heat treatment for 6-12 hours to obtain the porous lithium zirconate block. The porous lithium zirconate block prepared with the method has the characteristics of common continuous porous structure and the like.
