Piezoelectric ceramics production process introduced

About piezoelectric ceramics, we are not very curious about it? How it was discovered? What is produced? What are the applications? So, today, we are mainly talking about this production process. 

         Ingredients - mixing finely ground - burn-in - the second fine grinding - granulation - forming rows of plastic - sintered ceramic - contouring - Set electrode - aging test. 

         Detailed process: First, the material for impurities and dehumidification, and then add the appropriate amount of additive ingredients according to a certain percentage. The production of raw materials after mixing finely ground, the requirement is consistent particle size, high temperature burn-in, carry out the powder reaction needs to be finely ground again. Spray granulation, the particles according to the requirements and good manufacturing combined into a desired shape of the blank, the blank binder removed, using high-temperature sintering ceramics, porcelain and look for grinding to the desired size. Finally, the conductive electrode surface of the ceramic molding, and stability testing.
