Etching Studies of Gel-Grown Crystals: (100) Faces of Potassium Dihydrogen Orthophosphate

Suparna Sen Gupta, Tanusree Kar and Siba Prasad Sen Gupta

(Received July 28, 1992; accepted for publication November 21, 1992)

Microscopic observations of the chemically etched prismatic (100) faces of single crystals of KDP (KH₂PO₄), grown from modified double diffusion gel technique, revealed the presence of hillocks and etch spirals. Both edge and screw dislocations were clearly identified with suitable etchants. Influence of various alcohols and acid concentration on the pit morphology has also been observed. The features have been presented and discussed mainly from examination of optical micrographs.
