Abstract
WE have determined the elastic and piezo-electric coefficients of anhydrous ethylene diamine tartrate by measurements of the resonances of bars, and of square plates, cut at various orientations to the axes of the crystals. To find the piezo-electric coefficients, we have measured the capacitance of each specimen over a range of frequencies differing from the resonance frequency by ½–3 per cent. Although all the coefficients can be deduced from eighteen specimens1, we have used more than fifty different specimens so as to confirm our results fully.
