The milling was conducted in air with the vessel and balls (0 = 10 mm) made of Cr-Ni steel (sample BTV5/Fe), and ZrO2 (sample BTV5/Zr). The vessel was rotated at 550 rpm for. 3 hours, with a ball-to-powder weight ratio (BPR) of 30:1. Barium titanate (sample BT) was synthesized with the use of a high-temperature method as a reference sample [31].

The milled powders are characterized at different stages of milling by XRD, particle size analyzer, FESEM and DC electrometer. XRD analysis reveals that barium carbonate slowly transformed into barium strontium carbonate …

Cobalt ferrite (CoFe2O4)/barium titanate (BaTiO3) particulate composites exhibiting high magnetoelectric coefficients were synthesized from low-cost commercial precursors using mechanical ball milling followed by high-temperature annealing. CoFe2O4 (20 nm–50 nm) and either cubic or tetragonal BaTiO3 nanoparticle powders were used for the synthesis.

Summary Milling of BaTiO3 + 3 wt% ZrO2 was carried out in an attritor and a planetary mill during different times. When milled in air, BaTiO3 decomposes into BaCO3 + TiO2 and a solid solution betwe...

The (Ba1-xCax)(Ti0.92Sn0.08)O3 (x = 0 and 0.02) lead-free ceramics were prepared by using different ball-milling method and time (common ball milling 24 h, high energy ball milling 1 and 3 h). The two-step sintering method was used for sintered the samples. The densification, structure, dielectric and piezoelectric properties of the ceramics were investigated.

The changes of physico-chemical properties of mechanochemically pretreated (BaCO 3 +TiO 2 +PbO) powders were investigated. The values of apparent activation energy of BaTiO 3 formation calculated by the Freeman and Carroll method decrease with milling time. The changes of precursors density may be interpreted as a consequence of mechanochemical …
