AB  - BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. Optimization of sintering conditions indicated that temperature of 800 °C and time of 2 h after pressing at 9 t/cm2 provided ceramics samples with the highest density (up to 96% of theoretical density) and the lowest content of secondary phases. Ferroelectric and magnetic characterization was performed on two selected ceramics samples with the highest densities. Ceramics obtained from the powder synthesized by the hydrothermal method showed greater lattice distortion along [1 1 1] axis and smaller grains, which resulted in larger values of electric polarization at room temperature. It also exhibited less Fe(3d)–O(2p) orbital overlapping due to a larger FeOFe bond angle, causing lower antiferromagnetic ordering and weak ferromagnetic behavior at low temperatures.

AB  - Multiferroic bismuth manganite (BiMnO3) is known as a material that exhibits both ferromagnetic and ferroelectric properties making it interesting for various technological applications. Unfortunately, preparation of BiMnO3 is not possible by a conventional solid-state reaction and it can form only from mixture of oxides at high pressures (>40 kbar). In this work single-phased BiMnO3 was prepared for the first time by mechanochemical synthesis in a planetary ball mill. A mixture of Bi2O3 and Mn2O3 was intensively milled in air atmosphere, using stainless steel vials and balls. According to analysis of XPRD results BiMnO3 obtained after milling for 240 min has a tetragonal structure with lattice parameters a = 3.9230 Å, c = 3.920 Å and a crystallite size of 16.8 nm. The cumulative energy introduced into the system during milling for 240 min was 401 kJ/g. It was found that the obtained powders were agglomerated. Corresponding agglomeration factors were calculated from the results of BET and particle size distribution analysis. © 2009 Elsevier Ltd. All rights reserved.

AB  - A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) Fe2O3 using high-energy ball mill. The products are characterized by X-ray powder diffraction technique. Influence of milling conditions: milling time from 5 min to 10 h, milling medium (steel or ZrO2) and injected mechanical power on unit-cell parameters and crystallinity of products, as well as on reaction kinetics are investigated and discussed.

AB  - ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based on sintering of a mixture of the constituent phases with the following compositions: ZnO phase uniformly doped with Co2+ and Mn2+; intergranular phase: γ-Bi2O3 stabilized with Mn2+ or Zn2+; spinel phase: Zn1.971Ni0.090Co0.030Cr0.247Mn0.090Sb0.545O4. As proved, the obtained varistors are composed of the same phases as those introduced into the system. The influence of composition as well as milling and sintering parameters on the varistor characteristics were investigated. Some varistor powder mixtures were intensively milled before sintering. As a result, high density ceramics with highly homogeneous microstructure were obtained after sintering.
