Ultrasonic Piezoelectric Ceramic Rings Process flow:


1. ingredients


Pre-material treatment, removal of impurities and moisture, and then weigh the various raw materials according to the formula, pay attention to a small number of additives to be placed in the middle of aniseed.


2. Mixing and grinding


The purpose is to mix and grind the various raw materials and prepare the conditions for complete solid-state reaction for pre-burning. Dry grinding or wet grinding methods are generally adopted. Small batches can be dry-milled, and large-volume batches can be ball milled or jet-milled with high efficiency.


3. Pre-burn


The purpose is to conduct solid-phase reactions of raw materials at high temperatures to synthesize piezoelectric ceramics. This process is very important. Will directly affect the sintering conditions and the final product performance.



4. Secondary fine grinding


The purpose is to finely mix the pre-fired piezoelectric ceramic powders and finely ground them, so as to lay a solid foundation for the uniform performance of the porcelain.



5. Granulation


The purpose is to make the powder form a high density of particles with good fluidity. The method can be performed manually but with low efficiency, and the current efficient method is to use spray granulation. This process is to add adhesives.



6. Molding


The purpose is to press the pelletized material into a desired preformed blank.


7. Rows of plastic


The purpose is to remove the binder added during the granulation from the blank.


8. Sintering into porcelain


The blank is sealed and sintered into porcelain at high temperature. This link is quite important.


9. Shape processing


The burned product is ground to the desired finished product size.


10. Being electrode


A conductive electrode is provided on the desired ceramic surface. The general method is silver layer infiltration, chemical deposition and vacuum coating.



11. High-voltage polarization


The internal domain of the ceramic is aligned so that the ceramic has piezoelectric properties.


12. Aging test


After the ceramic performance is stable, the indicators are checked to see if they meet the expected performance requirements.
