Abstract:
This study investigates the synthesis of novel magnetic materials via hydroflux synthesis, a method that combines flux-based and hydrothermal techniques. Single crystals of three novel alkali tellurate oxide-hydroxides were synthesized. One, CsTeO3(OH), is nonmagnetic and a new member of the series ATeO3(OH) (A = alkali). The other two phases contain magnetic Cu-Te substructures, one of which, KCu2Te3O8(OH), is structurally three-dimensional and undergoes several magnetic ordering transitions. The other, Cs2Cu3Te2O10, is structurally two-dimensional and remains paramagnetic above T = 2 K. These exploratory investigations of novel phase spaces reveal key factors, including hydroxide concentration, precursor solubility, and oxidizing power of the solution, in the formation and composition of alkali tellurate oxide-hydroxides.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
Crystal Growth: Principles of Crystallization
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...
