Summary: Single-phase lanthanum-modified bismuth ferrite multiferroic ceramics were synthesized using the RLS method, with studies conducted on their phase composition, crystal structure, microstructure, and dielectric properties. The optimal conditions for achieving a perovskite Bi0.9La0.1FeO3 structure were determined, with compacting pressure shown to greatly impact the dielectric constant of the material. The use of the RLS method under varying compacting pressures offers new possibilities for creating multifunctional multiferroics with controlled magnetoelectric coupling.

Summary: M-type strontium hexaferrite (SrM) was synthesized using co-precipitation technique with different sintering temperatures and mole ratios. The synthesized SrM was characterized and its properties were investigated. The structural parameters, particle size, and magnetic properties of the samples were found to vary with calcination temperature and composition. The synthesized SrM showed potential applications in magnetic recording media and photocatalysis due to its low coercivity, high saturation magnetization, and low band gap energy.

Summary: Densified MnZn ferrite ceramics were prepared using the cold sintering process under pressure, with an acetate ethanol solution used as the transient solvent. The effects of the transient solvent, pressure, and annealing temperature on the density, micromorphology, and magnetic properties of the sintered MnZn ferrites were studied. The cold sintering process, along with the transient solvent and high pressure, is crucial for achieving densified MnZn ferrite. Additionally, the annealing treatment is necessary to increase the density further and reduce power loss at high frequencies.

Summary: In this study, the interaction between Fe66Cr10Nb5B19 metallic glass and aluminum during spark plasma sintering (SPS) was investigated, revealing the formation of reaction layers around the Fe-based cores. The Vickers hardness of composites increased with higher sintering temperatures due to the formation of thicker reaction layers at the interface. Comparison with traditional sintering methods suggests that interfacial resistance may play a crucial role in influencing reaction advancement and formation of intermetallics in metal matrix composites.

Summary: The effect of co-doping of titania and manganese oxide at different weight percentages on sintering behaviour and mechanical properties of alumina were studied. The addition of doping reduced the sintering temperature and improved the density and mechanical properties of alumina. XRD analysis revealed the formation of R-TiO2 and alpha-alumina at low sintering temperature, which further reacted to form Al2TiO5 at higher sintering temperature. MnO2 did not react with alumina due to atomic radii mismatch. SEM showed abnormal grain growth with increasing sintering temperature and dopant composition.

Summary: The study aims to utilize red gypsum muds from a TiO2 plant in Tuscany, Italy to produce ceramic materials for construction industry based on the principles of circular economy. The characterization of the red gypsum muds reveals its consistent chemical and mineralogical properties over time, which makes it suitable as a secondary raw material for industrial ceramic production. Ceramic specimens fabricated using a high proportion of red gypsum waste (up to 70%) consists of anhydrite, pyroxene, and Fe/Ti oxides as the main crystalline phases embedded in a glassy compact matrix. The production of ceramic materials could provide a sustainable solution for the management of large volumes of red gypsum waste from TiO2 plants.
