Behaviour of Pyroelectric Crystals

Article metrics


IN some simple demonstration experiments using liquid air we repeated many of the interesting observations reported by L. Bleekrode1 and by Miss M. E. Maurice2 on the demonstration of electric lines of force around pyroelectric crystals. As these papers may have escaped the notice of some mineralogists and crystallographers, we feel it may be helpful to direct attention to what, in our estimate, is the simplest and most striking way of demonstrating the phenomenon of pyroelectricity.
