Growth of ytterbium tartrate trihydrate crystals in silica and agar‐agar gels and their characterization

Abstract

Single crystals of ytterbium tartrate trihydrate have been grown by gel method using silica and agar-agar gels as media of growth. The medium of growth influences the morphology of grown crystals, silica gel yielding single and polycrystalline in the form of spherulites whereas agar-agar gel leading to growth of single and twinned crystals. Materials grown as single crystals have been characterized by using optical and scanning electron microscopy (SEM), EDAX, XRD, FT-IR, CHN and thermogravimetric techniques. The stoichiometry of the grown single crystals is suggested to be Yb(The FT-IR spectrum shows the presence of singly as well as doubly ionized tartrate ligands. Results of thermal analysis indicate that the material is thermally stable up to a temperature of 200°C.

Growth and characterization of a new polymorph of lead succinate: A promising NLO material

“…The crystallization of lead succinate was accomplished using single gel diffusion technique [8]. The crystals were grown in a single glass tube of length 20 cm and diameter 2.5 cm.…”

Physical and Optical Study of Cobalt Oxalate Single Crystals Grown by Agar-Agar Gel Method

“…Hence it is wide transparent crystal for wide range of wavelength (300-900). The wide band gap of CoC2O4 crystals confirms the less absorbance in visible region (Arun K.et al, 2008;Want B.,2006;Rohit P.S..,2020). The cobalt oxalate crystal can be used for the nonlinear optoelectronic device fabricating applications.…”

Polar Ordering of Macromolecular Chains in Composite Materials: Calcium Carbonate and Calcium Oxalate

“…To generalize the concept of polar composite formation, we also investigated in vitro composites grown in biopolymers other than gelatin. Will polarity formation also be observed for composite grown in polysaccharides, namely, agar–agar , and carrageenan? , Despite them being structurally very different from collagen (polysaccharides vs protein), chirality and more importantly polar groups are present along the macromolecular chain. Agar is a heterogeneous polysaccharide composed of a mixture of agarose and agaropectin.…”
