Surface studies on (111) faces of sodium bromate crystals grown from aqueous solution show the presence of growth steps. A new etchant consisting of a mixture of 8 parts of glacial acetic acid and 2 parts of formic acid, to which 3 mg/cc of cupric nitrate is added, reveals the dislocation sites on (111) faces of these crystals. The etching action on (111) and ( 111 ) faces is different. Different microhardness values are recorded on (111) and ( 111 ) faces of these crystals. The difference in etching action as well as in microhardness values on ( 111 ) and (111) faces is discussed.
