“…Since the main component of these materials is lead, therefore, looking for lead-free materials with optimal parameters that can replace environmentally harmful lead materials is an important issue. The group of lead-free materials includes: BaTiO 3 , SrTiO 3 , BiFeO 3 , Bi 0.5 Na 0.5 TiO 3 , K 0.5 Na 0.5 NbO 3 , Na 0.5 Bi 0.5 TiO 3 , BaFe 0.5 Nb 0.5 O 3 and composites and multi-component compounds obtained on their basis [10][11][12].…”

In the paper the multiferroic (ferroelectric-ferromagnetic) composites based on ferroelectromagnetic/ferroelectric (BaFe 1/2 Nb 1/2 O 3 (BFN)) powder and ferrite powder (zinc-nickel ferrite) were obtained by two technological methods. In the composite samples the ratio of the ferroelectromagnetic/ferroelectric powder to the magnetic powder was equal to 90:10. The ceramic powders were synthesized by the classical technological method using powder calcination/solid state synthesis, while densification of the composite powders (sintering) was carried by two different methods: (i) Free Sintering method (FS), and (ii) Spark Plasma Sintering (SPS).At the work, a comparison of measurement results for composite samples obtained by two sintering methods was made. The studies included the following analysis: DTA, XRD, SEM, DC electrical conductivity, electric permittivity and magnetic properties. The result of measurements presented in the work revealed that the ceramic composite obtained by two different technological sintering method (classical technology -Free Sintering method and Spark Plasma Sintering technique) can be promising lead-free materials for functional applications, for example in sensors for magnetic and electric field.
