Embodiment Construction
[0026] A method for preparing YAG transparent ceramics by gel injection molding; the method includes the preparation of YAG ceramic slurry, vacuum defoaming, catalyst addition, injection into mold curing, demoulding, drying, debinding, and firing; specifically includes the following step:
[0027] Step 1. Follow Y 3 Al 5 o 12 The stoichiometric ratio of the molecular formula weighs Y 2 o 3 Powder, Al 2 o 3 The powder is used as a ceramic powder, and a sintering aid is added to obtain an oxide mixture;
[0028] Step 2: Premix the oxide mixture with balls and a solvent to form a premixed solution, and mix and ball mill for 15 to 24 hours to obtain a mixed slurry;
[0029] Step 3. After the mixed slurry is dried in an oven, calcined in a muffle furnace, and sieved to 100-200 mesh as raw material powder for gel injection molding;
[0030] Step 4, add raw material powder and defoamer to the Isobam solution, and stir with a stirrer at a constant temperature;
[0031] Step 5...
