Study of flux crystal growth peculiarities, structure and Raman spectra of double (Mn,Ni) 3 BO 5 and triple (Mn,Ni,Cu) 3 BO 5 oxyborates with ludwigite structure

Crystallization of heterovalent double (Mn,Ni) 3 BO 5 and triple (Mn,Ni,Cu) 3 BO 5 oxyborates with the ludwigite structure is studied in fluxes based on Bi 2 Mo 3 O 12 diluted with Na 2 CO 3 or Li 2 CO 3 carbonates. Single crystals of five (Mn,Ni) 3 BO 5 and three (Mn,Ni,Cu) 3 BO 5 compounds with di...

Description
Summary:Crystallization of heterovalent double (Mn,Ni) 3 BO 5 and triple (Mn,Ni,Cu) 3 BO 5 oxyborates with the ludwigite structure is studied in fluxes based on Bi 2 Mo 3 O 12 diluted with Na 2 CO 3 or Li 2 CO 3 carbonates. Single crystals of five (Mn,Ni) 3 BO 5 and three (Mn,Ni,Cu) 3 BO 5 compounds with different cation ratios are obtained. The ion concentration is determined from the analysis of the lattice parameters by powder and single crystal XRD. The comparative analysis of the polarized Raman spectra of double and triple ludwigites is presented. The actual high nickel and small copper concentrations in the crystals are discussed. The hierarchy of chemical bonds in the fluxes used in addition to the approach involving stabilization of the manganese valence state using solvent components is estimated.
