Quartz Crystals Are An Important Electronic Material

Quartz crystals are an important electronic material. Quartz wafers cut in a certain direction, when subjected to mechanical stress, will generate an electric field or charge proportional to stress, a phenomenon known as positive piezoelectric effect. Conversely, when the quartz wafer is subjected to an electric field, it generates a strain proportional to the electric field. This phenomenon is called the inverse piezoelectric effect. The combination of positive and negative effects is called the piezoelectric effect. Quartz crystals not only have a piezoelectric effect but also have excellent mechanical properties, electrical properties, and temperature characteristics. The resonators, oscillators and filters designed and manufactured using it have outstanding advantages in frequency stabilization and frequency selection.
