Etching Morphology and Symmetry of TeO_2 Crystal

Ya Fang

Abstract

The etching morphologies of TeO2 crystal on (110) and (001) faces were observed by means of chemical etching and analyzed with the theory of symmetry group. The morphologies of etch pits are very special compared with the tetragonal system crystal with 422 point group. The morphologies of etch pits by theoretical analysis are in conformity with the experiment. It shows that the patterns of etch pits consist of {110} planes. It is clear that the habitual plane of crystal is {110} plane.
