Beyond high-temperature equipment core scenarios, piezoelectric ceramics have permeated more related fields, forming technical synergistic effects. In the field of ultrasonic testing, they can be made into high-temperature ultrasonic probes to perform non-destructive flaw detection on equipment such as high-temperature pipelines and boilers, detecting internal cracks, corrosion, and other defects without affecting equipment operation; in the energy field, high-temperature piezoelectric ceramics can be used in waste heat power generation systems to convert vibration energy in industrial high-temperature environments into electricity, achieving energy recovery and reuse; in the precision manufacturing field, micro-displacement platforms in high-temperature environments often use piezoelectric ceramics for driving, relying on their nanometer-level positioning accuracy to meet the high-precision processing requirements of aerospace components and other parts; in the ultrasonic e-cigarette field, piezoelectric ceramics are even the core material driving industry innovation. Ultrasonic e-cigarettes differ from traditional heating atomization methods by achieving e-liquid atomization through the inverse piezoelectric effect of piezoelectric ceramics—special piezoelectric atomization plates generate high-frequency vibrations of 35kHz-250kHz under the action of electric signals, breaking the e-liquid into small and uniform droplets, avoiding the burnt substances that may be produced by high-temperature heating and improving usage safety. Piezoelectric ceramics suitable for this scenario, such as TPY-43 formula products, have advantages such as large atomization volume, strong anti-dry burning capability (can withstand dry burning for 3 minutes), and resistance to acid, alkali, and oxidation. Their bright white glass enamel electrodes have high hardness and are not prone to scaling, which can significantly extend the service life of e-cigarettes. At the same time, piezoelectric ceramics can achieve miniaturized design, with some atomization plates having a thickness of no more than 1.5mm, meeting the product requirements of e-cigarettes for portability and promoting ultrasonic atomization technology to become an important development direction in the e-cigarette industry.

It is worth noting that different application scenarios have varying performance requirements for piezoelectric ceramics. For high-temperature applications, the Curie temperature needs to be increased by adjusting the material composition (e.g., introducing elements such as niobium and tantalum), while the ultrasonic e-cigarette field focuses more on optimizing the piezoelectric constant and mechanical strength. With advances in material technology, the application of piezoelectric ceramics will expand from monitoring and control in traditional industries to precision driving in consumer electronics and other diverse directions, providing core material support for the intelligent upgrading of various industries.
