We report X-ray diffraction and electron spin resonance (ESR) measurements of the effect of SrTiO3 ceramics doping using Cu2+ ions. ESR measurements reveal two kinds of Cu2+ centers in weakly (0.2–0.5 mol% Cu) doped SrTiO3. Both kinds of centers ha

The paper examines the phase transformations and synthesis of cordierite under solid-phase sintering using different natural and synthetic minerals, including binary compounds (mullite, spinel, enstatite) formed in intermediate stages. It is establis

The paper examines the mechanochemical activation of starting minerals (kaolin, pyrophyllite, and talcum) and their effect on the solid-phase synthesis and properties of cordierite. Binary oxide compounds (spinel, mullite, enstatite, forsterite) are

Physicochemical research is conducted to examine the phase formation under dynamic and static annealing of MgO–Al 2 O 3 –SiO 2 tempered glass (composition range adjacent to stoichiometric cordierite). Thirty glass compositions are examined in thi

ESR investigation of Sr 1 − x Ba x TiO 3 and Sr 1 − x Ca x TiO 3 at x = 0.01, 0.02, 0.04 and 0.06 was carried out in 3 cm frequency region at T = 300 K and T = 77 K. The observed spectra were identified as originating from Mn 4 + , Cr 3 + , Fe 3

The catalytic activity of soot filters for internal combustion gas exhausts made from synthetic cordierite with a catalytic covering of transition metal oxides (Co3O4, MnO2, CuO, Cr2O3) or binary oxides (CuCr2O4, CuCo3O5, Co3MnO6, CuMnO3) has been st

ESR study of BaTiO3 ferroelectrics doped with cerium or with niobium and strontium, both types of samples being doped with manganese, was performed at room temperature. In the samples of the first type the most intensive line with g-factor 1.9612 was

We report magnetization measurements and magnetic resonance data for SrTiO3 doped by manganese. We show that the recently reported coexistent spin and dipole glass (multiglass) behaviours are strongly affected by the distribution of Mn ions between t
