“…Mechanism of dendrite crystal growth was studied by Fujiwara and Nakajima [14]. Dendrite type growth morphology has been observed by several authors in the gel grown crystals, such as lead tartrate [15], cadmium tartrate [16], ammonium tartrate [17] and lanthanum tartrate [18]. In the present study to grow lead and cobalt mixed levo tartrate crystals, the supernatant ions of Pb +2 and Co +2 slowly diffused into the gel medium where they react with tartrate anions already present.…”

Lead-cobalt mixed levo tartrate crystals for different compositions of lead and cobalt were grown by using single diffusion gel growth method in silica hydro gel medium. Long and dendrite type white crystals as well as spherulitic crystals were obtained. The metallic composition in the crystals was estimated by EDAX. It was found that the metallic composition in the crystals did not vary as per the composition of supernatant solution, i.e., lead content was found more than cobalt content. The powder XRD suggested the orthorhombic nature for all crystals. The grown crystals were characterized by FTIR spectroscopy and thermal studies. The FTIR spectra revealed the presence of water molecules, O-H, C-H, C-O and C=O functional groups. The thermo-grams suggested that the crystals were thermally unstable and decomposed into oxide through carbonate stage.

Lead-cadmium mixed levo tartrate crystals for different compositions of lead and cadmium were grown by using single diffusion gel growth method in silica hydro gel medium. Long and dendrite type white crystals as well as star type crystals were obtained. The metallic composition in the crystals was estimated by EDAX. It was found that the metallic composition in the crystals vary as per the composition of supernatant solution, i.e., lead content was found more than cadmium content. The powder XRD suggested the monoclinic as well as orthorhombic nature. The grown crystals were characterized by FTIR spectroscopy and thermal studies. The FTIR spectra revealed the presence of water molecules, O-H, C-H, C-O and C=O functional groups. The thermo-grams suggested that the crystals were thermally unstable and decomposed into oxide through oxalate as well as carbonate stages.

ABSTRACT:Metal tartrate compounds find various applications. Lead tartrate finds application as additive in gasoline to prevent knocking in motors and calcium tartrate is well known for its ferroelectric applications. In the present study, lead and cobalt mixed levo-tartrate crystals were grown using silica hydro-gel as growth medium. Dendrite crystals were obtained at the gel-liquid interface. The crystals were characterized by Thermo gravimetric analysis and kinetic as well as thermodynamic parameters were evaluated for the dehydration and carbonate stage by C-R relation.
