Popis: The defect distribution of grown Langasite crystals as different growth conditions and selective chemical etching on La 3 Ga 5 SiO 14 single crystals of various etchants were investigated. The applications of piezoelectric devices were shown to be necessary to ensure a high surface finish. Colloidal silica was found to produce the best polishing effect and H 3 PO 4 -based etchants were shown in distinct selective etching effect and HF-based etchants were shown in reduction of roughness.
