2. Mixing and grinding: The purpose is to mix and mix various raw materials and prepare conditions for complete solid phase reaction for pre-firing. Generally, dry grinding or wet grinding is adopted. Dry grinding can be carried out in small batches, and agitation ball milling or airflow pulverization can be adopted in large batches with high efficiency.
Third, the pre-burning: the purpose is to carry out solid phase reaction of each raw material at high temperature to synthesize piezoelectric ceramics. This process is very important. Will directly affect the sintering conditions and the performance of the final product.
Fourth, the second fine grinding: the purpose is to re-sinter the pre-fired piezoelectric ceramic powder and finely grind it to lay a good foundation for the uniform performance of the porcelain.
5. Granulation: The purpose is to form a high density of fluid particles with good density. The method can be carried out manually but with low efficiency, and the efficient method is spray granulation. This process involves the addition of a binder.
6. Molding: The purpose is to press the pelletized material into the desired preformed blank.
7. Distorting: The purpose is to remove the binder added during granulation from the blank.
8. Sintering into porcelain: The blank is sealed and sintered into porcelain at high temperature. This link is very important.
Nine, shape processing: grinding the finished product to the required finished product size.
X. Electrode: Place a conductive electrode on the desired ceramic surface. The general methods are silver layer infiltration, chemical deposition and vacuum coating.
XI. High-voltage polarization: The ceramic internal domains are aligned, so that the ceramic has piezoelectric properties.
12. Aging test: After the ceramic performance is stable, the indicators are tested to see if the expected performance requirements are met.
