AbstractSamarium chloride-thiourea-l-tartaric acid (SCTuT): a semi-organic material was prepared in the form of a single crystal with an orthorhombic crystal structure and a space group Pnma. The crystallinity and purity of the single crystals were tested by powder X-ray diffraction. The scanning electron microscopy (SEM) analysis shows the rod-like microstructure. Energy dispersive X-ray analysis has confirmed the elemental composition. Fourier transform infrared and Raman spectroscopy analysis established the mode of coordination and functional groups. The thermal effects such as dehydration, melting and decomposition, etc. were observed by the thermogravimetric and differential thermoanalytical (TGA/DTA) analysis. Linear and non-linear characteristics of the compound were studied in detail. The optical band transitions due to C=O and C=S chromophores remain active in grown crystals and thus are recorded in the UV-Vis optical spectrum. The crystals possess finite values of non-linear absorption, non-linear refraction and third order nonlinearity as confirmed by Z-scan experiments.

The purpose of this study was to study the growth of struvite crystals from the effect of adding tartaric acid additives to an aqueous solution containing Mg2+, NH4+, and PO43-with a molar ratio of 1:1:1. The results of the study, it was found that the more the concentration of tartaric acid additive was added, it got smaller the rate constant was. By decreasing the value of the constant rate, the growth of struvite crystals also decreased then the growth of struvite crystals became inhibited. On the other hand, struvite has the potential to be used as a fertilizer. The concentration of tartaric acid also had a significant effect on controlling the production of struvite. The optimum crystal mass was obtained at a concentration of 20 ppm tartaric acid, a temperature of 40oC and a stirrer rotation of 300 rpm so that it can be applied in manufacture industry of struvite fertilizer.

Crystallization of Al(OH)3 from the caustic soda solution is the most important part of the Bayer process for alumina production because several phenomena which determine the properties of precipitated Al(OH)3 occur simultaneously. These processes are nucleation, agglomeration and Al(OH)3 growth. In this paper we have investigated the influence of tartaric acid on agglomeration, nucleation and Al(OH)3 crystal growth processes. The results have shown the inhibitory influence of these impurities on the phenomena mentioned above.

Crystal Growth Mechanism

Morphological features of montmorillonite aggregates in a large number of samples suggest that they may be formed by a dendritic crystal growth mechanism (i.e., tree-like growth by branching of a growth front).
