Abstract:

Quartz crystals containing V5, Ga3, Mg2, Ge4 and Zn2 were grown. Kinetics of growth, segregation of the impurities and mechanical Q values of the crystals were investigated. Electron probe analysis has revealed in the grown crystals circular defects, some 2 - 15 microns in diameter. All investigated impurities were found to concentrate preferentially in these defects. Preliminary results have shown comparatively higher Q-values in Zn2 containing crystals. Radiation effects were investigated in various natural and synthetic resonators, before and after sweeping-in various monovalent ions. Thermoluminescence and thermally stimulated currents in the irradiated crystals were examined and a possible correlation between these properties and the piezoelectric properties was indicated.
