Method for preparing Re:YAG transparent ceramic through gel injection mold forming
The present invention discloses a method for preparing a Re:YAG transparent ceramic through gel injection mold forming, and belongs to the technical field of special optical ceramic manufacturing processes. The method specifically comprises: adopting a certain amount of an organic monomer and a certain amount of a cross-linking agent, dissolving in water, carrying out ball milling mixing on the obtained solutions and ceramic powder for 20-40 h, adding a certain amount of an initiator and a certain amount of a catalyst, carrying out vacuum defoaming, directly injecting into a mold with a certain shape, placing into an oven with a temperature of 50-100 DEH C, initiating a reaction, and solidifying to obtain a green body. With the forming way, the gel has the network macromolecule structure, the ceramic particles are cured in the network molecule structure, the solute in the solvent can not migrate along with the directional movement of the solvent during the drying process, the component and the structure of the obtained green sheet are uniform, the density gradient produced from slurry injection forming and dry pressing forming is avoided, the gas pore in the green body is easily removed during the vacuum sintering process, and the good ceramic body with characteristics of high transparency and whole uniformity is obtained.
