A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Abstract We present a study of multiferroic properties of YFeO3 synthesized by means of high-energy ball milling assisted by annealing at low temperature. Fe2O3 and Y2O3 powders were mixed in a stoichiometric ratio, milled for 5 h, pressed and annealed at temperature from 773 to 1073 K. X-ray diffraction (XRD) analysis confirmed the formation of single-phase orthorhombic …

Crystal structure, and magnetic and dielectric properties were studied in Ti-doped YFeO3 polycrystalline samples. The crystal structure and chemical state of the Fe/Ti cations were characterized by a combination of X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). It is found that a narrow solid-solubility limit is achieved (~ 6%) and the d0–ness of Ti4+ …

Ball mill introduction. Structurally, each ball mill consists of a horizontal cylindrical shell, provided with renewable wearing liners and a charge of grinding medium. The drum is supported so as to rotate on its axis on hollow trunnions attached to the end walls (attached figure 1 ball mill). The diameter of the mill determines the pressure ...

The precursors mixed in a stoichiometric ratio to obtain YIG were milled at room temperature in a shaker mixer mill with a ball:powder weight ratio of 10:1. A partial synthesis of YIG was achieved after 9 h of milling time by using the three sources of iron; however, a significant fraction of the product was the perovskite YFeO3.

Similar behavior was reported by Baños et al., they demonstrated that high-energy ball milling increases internal energy of powders, reducing the temperature necessary for YIG synthesis. The precipitation of other phases can be attributed to the low solubility of Bi 3+ cations into YFeO 3 structure, accordingly the excess of Bi 3+ cations ...

The orthorhombic YFeO 3 or yttrium orthoferrite, having distorted the perovskite structure, crystallizes in the centrosymmetric space group Pnma, with lattice parameters a = 5.5946 Å, b = 7.6040 Å, and c = 5.2790 Å. The centrosymmetric nature of this material is responsible for ferroelectric and weak ferromagnetic behaviors at room temperature.
