Crystal stability
WebJun 2, 2006 · These considerations are now extended to crystals of general symmetry, and it is shown that the anomalous temperature dependence of certain dielectric, piezoelectric, and elastic constants in the paraelectric phase of ferroelectric crystals can be described and correlated in a very natural way in terms of crystal stability. WebA crystal is a small wafer of high grade quartz cut at a certain angle and to a certain size. Thinner cuts give higher frequency crystals, approximately 0.15 mm at 15 MHz. ... and good stability over temperature. (L1,C1 and R1 represent fundamental operating frequency. L2, C2, R2, L3, C3 and R3 represent overtone frequency operation.)
