Mechanical properties and dimensional stability of the quartz crystal's different axis

Quartz material is used in quartz accelerometer sensitive devices, but quartz crystal growth process leads to the different properties in each directions. This article chooses the ZD-1 homebred man-made optics quartz crystal on mechanical properties and dimensional stability of research. The microstructure observation shows that quartz crystal and there are a high degree of orderly amorphous, and there are not other defects. In three axis, perpendicular to the Z axis (optical axis) bending strength is to 194 MPa; The Z axis direction has the most stable performance, the thermal expansion is between 5.0×10 ^-6/°C and 7.5×10 ^-6/°C.
