“…11 17 In particular, on the one hand they deteriorate pyroelectric figures of merit by decreasing the values of odd-rank tensors and increasing noise, but on the other hand they enhance electrical, mechanical and piezoelectric susceptibilities due to domain walls. 15 To our knowledge, very few attempts have been made to correlate physical properties of boracites to their domain structures. 18 19 The reason could be that for the experimental study of a ferroelectric material the interest usually focuses on single crystals which are both single domain electrically and untwinned crystallographically, so the starting point is to apply a poling process to the sample, thus 'destroying' its initial domain structure.…”

New iron-zinc chlorine single crystals of Fe1.5Zn1.5B7O13Cl boracite were grown by chemical transport reactions in closed quartz ampoules, at a temperature of 1173 K. The crystal structure was characterized by X-ray powder diffraction (XRD) using the Rietveld refinement method and belongs to the trigonal/rombohedral system with space group R3c (No. 161). The cell parameters were a = 8.5726(1) angstroms, c = 21.0116(4) angstroms, V = 1337.26(3) angstroms3 and Z = 6. The refinement successfully proceeded and ended with sound merit figure values chi2 = 2.25, R(B) = 6.12%. Chemical analysis was performed with X-ray energy dispersive spectroscopy (EDS) and X-ray fluorescence (XRF). Ferroelectric nano and micro reoriented domains were found in this material using polarizing optical microscopy (PLM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The examination by TEM showed that in the trigonal/rombohedral system of Fe1.5Zn1.5B7O13Cl nanodomain structures exist. Thin (50-100 nm) mostly planar domains parallel to (100) were frequently observed in Fe1.5Zn1.5B7O13Cl boracite.

“…The study of domain structures is important for understanding properties of ferroelectric materials because their properties are to a large extent determined by domain structures (Cao & Cross, 1994; Schmid & Tippmann, 1978). In particular, on the one hand they deteriorate pyroelectric figures of merit by decreasing the values of odd‐rank tensors and increasing noise, but on the other hand they enhance electrical, mechanical and piezoelectric susceptibilities due to domain walls (Fousek, 1992). To our knowledge, very few attempts have been made to correlate physical properties of boracites to their domain structures (Schmid & Schwarzmueller, 1976; Burzo, 1993).…”

SummaryThe domain structures of Zn 3 B 7 O 13 Cl, Zn 3 B 7 O 13 Br and Zn 3 B 7 O 13 I boracite single crystals were studied by means of polarized light in conjunction with electron microscopy. Single crystals of the three compositions were grown by chemical transport reactions in closed quartz ampoules, at a temperature of 900 ° C and were examined by polarizing optical microscopy (PLM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). For both PLM and SEM, the same as-grown samples were used without having to resort to metallization of the crystal faces. For TEM the single crystals were crushed and mounted on holey carbon films. Comparative electron microscope images were useful for revealing the domain structure of these ferroelectric/ferroelastic materials previously observed between the crossed polars of an optical microscope. X-ray diffraction analysis of the pulverized crystals was performed for this triad of halogen boracites containing zinc as a common metal.

“…The understanding of domain structures is essential not only from the point of view of technological applications of ferroelectrics but because the principal physical properties of these materials are mainly determined by the behaviour of domain structures (Cao & Cross, 1994). In particular, on the one hand they deteriorate pyroelectric figures of merit by decreasing the values of odd-rank tensors and increasing noise, but on the other hand they enhance electrical, mechanical and piezoelectric susceptibilities due to domain walls (Fousek, 1992).

SummaryCrystals of halogen manganese boracite, the mineral Mg 3 B 7 O 13 Cl, which is currently found in bedded sedimentary deposits of anhydrite, gypsum and halite, have been grown by chemical transport reactions and were examined by polarizing light microscopy and scanning electron microscopy. For both methods the same as-grown samples were used without having to metallize the crystal faces. Comparative electron microscope images were useful not only for observing the charging mechanism of an insulating sample bombarded by an electron beam but also for revealing the domain structure of these ferroelectric/ ferroelastic materials previously observed between the crossed polars of a light microscope. EDS qualitative analysis of the crystal faces was performed for the three compositions under study, i.e.
