Single Crystal Quartz Cut Into Wafer With Different Orientation
Piezo quartz is the highly symmetric shape of the single crystal,
is characterized by the arrangement of atoms and molecules have
rules well developed quartz crystal, appearance is the most
significant features rule configuration, the crystal quartz crystal
crystal face a total of 30, 6 m (cylindrical), six R surface (large
surface edges) six R surface (surface) edges six s surface
(three-way partial cone), Six X planes (tripartite partial planes),
the clip Angle of adjacent M plane is 60°, the Angle between
adjacent M plane and R plane and adjacent M plane and R plane is
38°13 ', and the Angle between adjacent S plane and X plane is
25°57 '.
