Abstract
Calcium tartrate tetrahydrate (CTT) single crystals doped with barium were grown by controlled diffusion in silica gel at ambient temperature. The max imum uptake of barium in CTT was determined. Effect of barium dopant on the growth and morphology of CTT was studied. The grown crystals were characte rized by chemical analysis, thermoanalytical techniques, X-ray diffraction and optical studies. Barium-doped CTT crystallizes in the monoclinic system . The crystals are optically biaxial and exhibit second harmonic signals gr eater than quartz. (C) 2000 Elsevier Science B.V. AII rights reserved.
