Synthesis and characterization of gel-grown cobalt tartrate crystals

FTIR and Thermal Studies of Gel Grown Lead Cobalt Mixed Levo Tartrate Crystals

“…Earlier Joseph et al [3] explained the growth of spherulitic crystals of iron tartrate in gel medium and also reported the spherulitic growth of iron and cobalt mixed tartarte crystals [19]. The lead tartrate crystals are white and dendrite in form [7] while cobalt tartrate crystals are dark brownish with spherical shape [5]. The proposed and estimated formula for the Pb Co mixed levo tartrate crystals are listed in the table 6.…”

“…Moreover, in metal tartrate compounds, the metal coordinates with hydroxyl and carboxylates groups; the change in O-H stretching vibration due to presence of cobalt in lead tartrate is thus confirmed. Metaloxygen vibrations for pure lead tartrate occur between 513.8 cm -1 to 605.4 cm -1 [7], while the same for cobalt tartrate occur below 500 cm -1 [5]. As shown in the table 1, the metal-oxygen vibrations for the mixed crystals of lead and cobalt occur between 505 cm -1 to 630 cm -1 , indicating no significant effect of cobalt on the metal-oxygen vibrations.…”

“…In the literature, many tartrate compounds are reported which have been grown by the gel technique, for example, iron tartrate [3], cobalt tartrate [4][5][6], lead tartrate [7], mixed iron-manganese tartrate [8] and ternary ironmanganese-cobalt tartrate [9] as well as ternary iron-manganese-nickel tartrate [10]. Carbonate solutions containing Co(II) tartrate complexes find application in an electrochemical procedure of anodic deposition of cobalt oxyhydroxide film on a glassy carbon substrate in an alkali medium [11], whereas, lead tartrate finds application as an additive in gasoline to increase the performance of the engine [12].…”

Thermal Study of Cadmium Levo-Tartrate Crystals

“…The supernatant solution containing cadmium nitrate solutions was poured on the set gel carefully without damaging the gel. 3 produced is very less in comparison to the nutrients being supplied to the growing crystals and hence no major limitation is imposed [5][6][7][8].…”

“…Gel acts as a 3 dimensional crucible which supports the growing crystal and at the same time yields to its growth without exerting major forces on it. In the literature, many pure tartrate compounds are reported which have been grown by gel technique, for example, iron tartrate [1], cobalt tartrate [2][3][4] and lead tartrate [5]. In the present work, pure cadmium levo-tartrate crystals were grown by gel technique.…”
