2. Ball milling: put the mixed powder into a ball mill for ball milling, so as to make it mix more evenly and have finer particles. The time and speed of ball milling need to be adjusted according to the properties of powder and the required particle size.
3. Drying: the slurry after ball milling is dried to remove water. The drying method can be natural drying or rapid drying with drying equipment.
4. Granulation: Granulate the dry powder to make it into particles with good fluidity, which is convenient for subsequent compression molding. The granulation method can be spray drying or rolling granulation.
5. Press molding: put the granular powder into a mold for press molding to make it into the required shape and size. The press forming method can be dry press forming or isostatic pressing forming.
6. Glue tapping: Glue tapping is carried out on the pressed blank to remove the organic matter and moisture in it and improve its compactness and strength. Glue can be discharged naturally or quickly by using a glue discharging furnace.
7. Sintering: the green body after glue discharge is put into a sintering furnace for sintering, so that it becomes a compact ceramic product. The sintering temperature and time need to be adjusted according to the properties of the powder and the required ceramic properties.
8. Post-treatment: The sintered ceramic products can be post-treated.
