ABSTRACT: The present-paper deals with tests of the polarization and
the.aub:--polarization of. BaTiO ceramics in rhombic phase#

This polarization,has been called the low-temperature pola-
r12ation. These tests were,made on the assumptio-A that it might
be possible',to obtain.bigher values of piezomoduli of ~eramice
in the jrhombia and tetragonal phase by such a polarization in~
relatively..smail'fields. The low-temperature sub-polarization
in-the.rhombic phase causes an increaae of the values of the
piezomoduli of.ceramics in the tetragonal phase. On heating
under the field the subpolarization cauceD an increase of the

'ABSTRACT: if the extraordinarily important r6le of the domains of the

properties and of the nature itself.of the ferroelectrical
phenomena is Ltaken Linto aocount~ the application of electron
microscopy for.the purpose of completing the laws concerning
the orientation of the domains (of the characteristic features
of their boundaries and of their dimensions) offer many poe-
sibilities. According to the authors' investigationst the
domain itructure of the ferroeloo,trics may be visualized by
of a translucent microscope according to the method
of the imprints. These imprints must reproduce the fine struc-
Card 1/4 ture of the electric field. This was possible because of the

existence of a natural raised profile (rellyef) of the ferro-
electric~poly-domain crystal. This raised profile of the
surface ielcaused by mechanical tensions on the boundaries
of the domains which, in turn, are caused by the interaction
of their electric dipoles. The use of a translucent electron
microscope and of colloid and coal imprinta permitted the
-detection of the domain structure on cryatals of barium ti-
and potassium sodium tartrato enlarged 25 000-fold.
The.domain'structure of the ferroelectrica may be observed
on imprints taken immediately from non-procensed crystals
and from etched.orystals. The authors etched crystals of
BaTiO in concentrated hydrochloric acid for 5 - 10 minutes.

structure of BaTiO in 1000-fold enlargement. With an 8000-

(25 000-fold) the details of the boundary.between the domains

is very interesting for the detection of some properties of

ABSTRACT: The changes in the . symmetry of crystals conditioned,.

of.sign,.change,of magnitude) in the specific rotation
Rf the plane of polarisation of light are investigated.
The specIfic.rotation in one direction is described by
an axial.tensor of symmetry 00 2 . The gyration
surface of a crystal can belong to one of the-four.'symmetry:
'groups 2.-2, 46ml 00: 2 and 0oloo The morphological

coincide with these groups or their sub-Sroups. Point
'groups which can show rotation are 1,2 394,6, 2, 3.-2$
