Reputation depends on quality, quality comes from Hard!
Alumina Ceramic:
Piezoelectric ceramics is an information-functional ceramic material that can convert mechanical energy and electrical energy into each other. Piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been widely used in medical imaging. Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by the material under the action of mechanical stress, causing the relative displacement of the internal positive and negative charge centers to be polarized, resulting in the opposite end of the material with the opposite sign of the trapped charge, ie piezoelectric effect, with sensitive characteristics, piezoelectric Ceramics are mainly used in the manufacture of ultrasonic transducers, hydroacoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, In addition to being used in high-tech fields, igniting and igniting devices and piezoelectric gyros are more dedicated to serving people in daily life and creating a better life for people.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
