Quartz Blanks - China

Quartz Blanks

This material consists of single-crystal right-handed a-quartz artificially grown bars which is intended for use in fabrication of piezoelectric for such as timing frequency control and frequency selection under hydro-thermal condition on a seed with its length along the Y axis.
