    • Abstract

       

      Etch pits produced by selective etchants such as 1 M HCl, 1 M HNO3, 4 M BaCl2, 4 M NH4Cl and 4 M NH4Cl-1 M HCl solutions on the as-grown {110} faces of barium oxalate dihydrate crystals are illustrated and explained. The kinetics of etching is studied. From Arrhenius plots, the activation energy of etching and the pre-exponential factor are computed. An empirical equation governing the kinetics has been suggested.
