Investigations on the Nucleation Thermodynamics of RbTiOXO4 (X= P or As) Crystals Grown from High Temperature Solution

The nucleation thermodynamics of RbTiOXO4 (where X= P or As) family crystals crystallizing from high temperature solution using the phosphate and tungstate solvents have been studied. Using the regular solution model and classical nucleation theory the nucleation thermodynamical parameters like interfacial energy, chemical potential, free energy change, critical energy barrier and radius of critical nucleus have been calculated which leads to better understanding of the nucleation process. Comparative study has also been made to investigate the metastable zone width of the above family crystals grown from different fluxes.

Keywords: RTP, RTA, flux, high temperature, nucleation
