About quartz resonate and quartz crystal

Quartz crystal resonator is called crystal, the component is mainly composed of quartz chip, base, shell, silver plastic, silver and other components, according to the package we divide the quartz crystal into two types of in-line and surface mount.Crystalis an important raw material is quartz crystal, quartz crystal is the famous piezoelectric material, used to carry the piezoelectric characteristics of the device, mainly for the production of piezoelectric resonators for frequency selection and control, which is characterized by high mechanical quality factor, Frequency with temperature changes. For example, quartz quartz crystal clock in the voltage produced by about 100,000 times per second oscillation, the clock accuracy is very high. Lithium niobate is also an excellent piezoelectric crystal, widely used in surface acoustic wave devices. It can also be used at high temperatures, even at 1000 ℃ high temperature lithium niobate piezoelectric transducers and no significant degradation.
