Synthesis and Characterization of Ferroferriborate (Fe₃BO₅) Nanorods

Abstract

Fe3BO5 nanorods with diameters from 4 nm to 16 nm and length from 43 nm to 60 nm are synthesized by a facile thermal decomposition of iron acetylacetonate and t‐butylamine borane (TBAB). TBAB is used to control the 1D growth and the aspect ratio of the nanorods. These Fe3BO5 nanorods are antiferromagnetic with TN = 174 K, which is higher than that of bulk Fe3BO5 (114 K).

Frequency-temperature dependent dynamics of dielectrics in ferric oxoborate Fe3BO6 of cocktail structure of nanorods

“…As a biocompatible material, Fe 3 BO 6 has a bright future for domestic color pigments, catalysts, biological barcodes, drugs and drug systems, or medicinal tools [13,14]. A nanoscale borate is rarely prepared so far except Fe 3 BO 5 rods made using a hydrothermal method [15], or a solution phase reaction [7], and spherical Fe 3 BO 6 particles made from a rheological phase reaction [7]. Our group used devitrification of series of iron borate glasses with different catalytic additives that tailors useful properties in small fibrils of ferrites, iron borates, or borates depending upon annealing in air [16,17].…”

“…The compound Fe 3 BO 6 belongs to an important family of iron oxoborates Fe 2þ Fe 3þ OBO 3 , Fe 2þ 2 Fe 3þ O 2 BO 3 , or Fe 3þ 2 Fe 3þ O 3 BO 3 and displays highly tailored electronic properties depending on iron valence Fe 2þ , Fe 3þ , and relative O 2À number density in a space lattice [1][2][3][4][5][6][7][8]. A canted antiferromagnet of 3d 5 (Fe 3þ ) spins on an infinitely large space lattice Fe 3 BO 6 displays a magnetic orientational phase transition from one weak ferromagnet state À 2 to another À 4 [3,9].…”

Growth of one-dimensional single-crystalline hydroxyapatite nanorods

“…Considerable efforts have been devoted to the synthesis of nanorod-shape materials and further to investigate their corresponding properties [3][4][5][6][7].…”

Magnetic and dielectric properties of Fe3BO6 nanoplates prepared through self-combustion method

“…Most of the studies are limited to bulk oxyborates prepared by a conventional solid state reaction. A nanoscale borate is rarely prepared so far except Fe 3 BO 5 nanorods are made recently using a hydrothermal method, 17 or a solution phase reaction, 8 and spherical Fe 3 BO 6 nanoparticles made from a rheological phase reaction. 6 Quite good numbers of studies are carried in authors' laboratory on the iron borate glasses with varieties of additives that yield small fibrils of ferrites and iron borates with tailored magnetic as well as dielectric properties.…”
