Abstract
IT has been shown1–3 that the application of a strong varying electric field (alternating, pulsating), but not a steady d.c. one, normally on a quartz plate during etching by hydrofluoric acid, results in the formation of two kinds of etch-figures, namely, the ordinary microscopic etch-pits (or hills), and the so-called electric figures of sizes visible to the naked eye, the latter being composed of fissure-like lines. It also has been demonstrated that the orientations of the electric figures produced on the three principal sections of quartz are useful for axes determination, and that certain crystal defects, undetectable by the conventional method of etching, can be easily located by the distribution of these figures.
