The current efficient method is to use spray granulation. The method can be carried out manually but the efficiency is low. (5) Granulation: The purpose is to make the powder form high-density particles with good fluidity. (4) Secondary fine grinding: The purpose is to vibrate and grind the pre-fired piezoelectric ceramic powder finely, so as to lay a solid foundation for uniform ceramic formation and consistent performance. This process is very important and will directly affect the sintering conditions and the performance of the final product. (3) Pre-sintering: The purpose is to synthesize piezoelectric ceramics by solid-phase reaction of each raw material at high temperature. Dry milling can be used for small batches, and agitating ball milling or jet pulverization can be used for large batches, with higher efficiency. Generally, dry grinding or wet grinding is adopted. (2) Mixing and grinding: The purpose is to mix and grind various raw materials to prepare conditions for pre-burning for complete solid-phase reaction. Note that a small amount of additives should be placed in the middle of the bulk. (1) Ingredients: Carry out pre-treatment of materials, remove impurities and damp, and then weigh various raw materials according to the formula ratio. The general process flow of piezoelectric ceramics: Using piezoelectric ceramics to convert electrical energy into ultrasonic vibrations can be used to find the position and shape of underwater fish, non-destructive testing of metals, ultrasonic cleaning, ultrasonic medical treatment, and various ultrasonic cutters, welding devices and Soldering iron, processing plastic and even metal.Ĭlick Here To See Piezo Ceramis Products The manufacturing process of piezoelectric ceramics There are flints made of piezoelectric ceramics in electronic lighters, and the number of ignitions can be more than 1 million. In terms of energy conversion, the use of piezoelectric ceramics to convert mechanical energy into electrical energy can be used to manufacture piezoelectric igniters, mobile X-ray power supplies, and shell detonating devices.

This wonderful effect has been applied in many fields closely related to people’s lives to realize functions such as energy conversion, sensing, driving, and frequency control. On the contrary, when an excitation electric field is applied, the medium will produce mechanical deformation, which is called the inverse piezoelectric effect. This is the positive piezoelectric effect. The so-called piezoelectric effect means that when some medium is subjected to mechanical pressure, even if the pressure is as small as sound wave vibration, it will produce shape changes such as compression or elongation, causing the surface of the medium to be charged. Piezoelectric ceramics are functional ceramic materials that can mutually convert mechanical energy and electrical energy.
