Product Description
AT ST Cut Quartz Crystal Round Blanks and Wafer
Piezoelectric materials exhibit a directionally related electric charge when subjected to pressure and conversely the application of an electric charge causes a directionally related force to be generated within the material. The application of an alternating electric field will cause the material to vibrate and subsequently mechanically resonate. The frequency of any mechanical resonance is determined by the physical dimensions of the material, the ‘cut angle’ with respect to the crystalline axis of the original mono crystalline crystal, the ambient temperature and any modifying effects of associated mechanical or electrical components.
The properties of crystallised quartz include its high chemical and mechanical stability and a low temperature coefficient, resulting in a small change in resonant frequency for any change in ambient temperature, together with a very high Q at resonance. It occurs naturally and all early experimental work was carried out using natural crystallised quartz.
