TL;DR: The relationship between ferroelectric domain growth and the size of crystallites in ultrafine BaTiO 3 powders has been investigated in this paper, where the authors showed that the presence of Ferroelectric domains depends on the constraining force introduced by hard agglomeration of the crystallites.

TL;DR: In this paper, the effects of particle size of fine BaTiO3powder on dielectric properties of polyvinylidene fluoride (PVDF) composites were investigated.

TL;DR: In this paper, the XRD pattern and thermal behavior of barium titanyl oxalate tetrahydrate (BTOT) were investigated and it was shown that BTOT crystallizes in the monoclinic system, 2/m, with unit cell dimensions of a= 14954 A, b= 19332 A, c= 13947 A, and β= 10643° Unit cell content (Z) is 12 and the Bravais lattice is P Theoretical density is 231 g/cm3 At a relatively low temperature (∼60°C

TL;DR: In this paper, the length-to-diameter ratio of a single-crystal-type α-Al 2 O 3 nanofiber was examined using HR-TEM techniques.

TL;DR: The effects of mechanical treatment on the phase transformation and sintering of nano-sized g-Fe2O3 powder were studied in this paper, where the authors obtained a uniform fine-grained microstructure.
