Synthesis and molecular structure of barium titanate ceramic BaTiO3 (BT) and its applications

Complexity science applications to piezoelectric materials that cannot grow these materials for decades. Until World War I for the first time in piezoelectric sonar (sound navigation and sonar) were used. In 1917، Powell et al Langsyne Ultra-Sonic، a piezoelectric transducer، which was designed for submarines، a thin quartz crystal was it had the capabilities of the ultrasound transducer (mechanical waves، high frequency KHZ20) into electrical signal Electrical conversion and vice versa، and thus the desired object is able to accurately measure all of them.
