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

Abstract

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.

Synthesis and characterization of novel bio‐material: Nano composites of hydroxyapatite and curcumin

“…The impedance spectroscopy is employed by several authors to characterize various samples of crystalline and nano crystalline nature, [49][50][51][52][53] CdS nano-particles, 49 manganese-mercury thiocynate, 50 Co implated ZnO single crystals, 51 recently, lead-iron levo-tartrate 52 and lead-cobalt levo-tartrate crystals. 53 The Nyquist plots of Zʺ vs Zʹ are drawn for the pure HAP and Cur-HAP nano composites. Figure 5 shows the Nyquist plot of the pure HAP, consisting two semicircular arcs.…”

Study of Growth and Characterization of Cobalt Tartrate Crystals

“…The peak at 1427.37cm -1 is the band corresponding to OH in plane bending. The band at 1369.50cm The band observed at 557.45 -489.94cm -1 corresponds to metal oxygen bonding [34][35][36][37]. Table 3shows the FTIR spectral analysis of cobalt tartrate crystal.…”

Growth, Characterization and Morphology Study of Gel-Grown Lead-Cadmium-Mixed Levo-Tartrate Crystals

“…There are reports available in literature on thermal studies on metal tartrate systems, for example, cadmium tartrate [4], cobalt tartrate [7], ternary iron-manganese-cobalt tartrate compound [11], ternary iron-manganese-nickel tartrate compound [12], lead-iron mixed levo tartrate crystals [26] and lead-cobalt mixed levo tartrate crystals [27]. Table 4 gives details of the thermal decomposition of the samples (I-II) for the crystals grown at gel-liquid interface and below gel-liquid interface with theoretically calculated and experimentally obtained mass loss values, respectively.…”
