All kinds of frequencies from 1.8432MHz to 60MHz are available. The various kinds of quartz resonators manufactured from high quality artificial quartz crystal blanks are used as the key units for frequency stabilizers with high precision and high stabilization, which may be widely used in electronic equipment, satellite communication, high stabilized measuring apparatus and watch industry. The various quartz crystal wafers in cutting type are the ideal materials used in optics and acoustics of other applications, such as sensors and ultra-sonic transducers.
