TOPIC TAGS: selenide, praseodymium, neodymium, samarium, europium
ABSTRACT: Polyselenides of praseodymium, neodymium and samarium of the Me2S4 type
were prepared by reacting the respective metal oxides with hydrogen selenide at
750-800C. Sesquiselenides of these metals were prepared by similar reactions
at 1100-1200C, or by thermal decomposition of the polyselenides in hydrogen or in
an inert gas. The reaction of europium with hydrogen selenide at 1100C yielded
europium monoselenide (EuSe); europium selenides with a higher selenium Content were
not obtained. The preparative procedure of the selenides, their properties ' their
stability in various media, and the preparation of compacted selenide specimens are

ABSTRACT: The temperature dopendence of the relative elongation of EuS, 13US6, La2503,
C02SQ3, Pr23031 Nd2SO3, NdZ3031 SM26 S031 Fjm2j-l 1 Pr202To and Sm2O2Te was studied in tho
range from room tomporaturo to 600 K. The m6autiroments were made with a quartz dila-
topieter. In DaDGing from the rare earth metals to their compounds with an Ionic-cova-
lent bond character$ the thermal expansion coefficient a increases (With the exception
o fGuropium), apparently because of an increased anhannonicity of the thermal ribra-
tions of the crystal lattice. Zip vaj-~,o of ri of the chalcogenides increases In tho
rare earth series and in passing from sulfides to solanides; this is also due to in-
croased anharmont city. The a valuos of ovrtel-luridos are Intermediate between those
of oxides and sesquisulfides. From the a values, the Dbbye tomporatures 0 of the com.-
pounds were calculated and found to decrease withincreasing atomic number of the rare

A13STRACT: The interaction between Nb and Ta metal powde s and H2S was investigated witIA '
the aid of the setup shown in Fig. 1, in the presence of a hydrogen flow rate of 0. 2 liter/mln_~
Following purification to remove oxygen, a current of hydrogen is passed over molten sulfur
in reactor 4 where it interacts with S vapors so as to form H2S which then proceeds to qua4~.
reactor 5 which contains a porcelain boat with the suspension of Nb or Ta. The resulting ;.,
(1NbS1 6at 1000-130011C, TaS 2 at 1400T) sulfide is then cooled in a H25 current and analyzed
for dt~ content of metal and total and free sulfur. NbS1 6 is a black-colored powder which does
not decompose in air. Radiographic examination show;N that the lattice parameters of NbSl.

PURPOSE AND COVERAGE: This monograph attempts a systematic review of
Soviet and Western research on selenides and tellurides of the
rare-earth metals and actinides for the benefit of the engineers,
technicians, and scientists working in the field of research and
application of rare-earth metals and actinides. An up-to-date
collection of research data, mostly Western, was systematically pre-,
sented in this monograph. The data concern crystal strucLare,
physical and chemical properties, methods of preparation and chemi-
cal analysis of aelenides and tellurides of rare-earth metals and
actinides (uranium and thorium). A general evaluation of the data
presented was made in the foreword. The Soviet scientists, V. P.

Luzhnaya, V. I. Spitsyn, and Ye. I. Yarembash from Moscow, and G. V.
Samsonov and S. V. Radzikovakaya from Kiev are considered to be the
chief contributors to the research on preparation and properties of
the rare earth metal chalcogenidea. The possibility of the applica-
tion of these compounds in high-temperature semiconductor elec-
tronice is stressed in the foreword. Included in the monograph are
the most recent (1965) contributions by the authors to knowledge of
physical and chemical properties dnd to preparation of certain
selenides and oxytellurides of rare-earth metals. Chapters I,
III, IV, V, and VII were written by V. A. Obolonchik, II and V1
by G. V. Lashkarev. Thanks are expressed to A. M. Golub, professor,
PhD in chemistry, and to Yu. B. Paderno, Candidate of Technical
Sciences. There are 121 references, including about 30% Communist
:ources.

TITLZs Low-Power Servosystem With Transistors
PERIODICAL; Avtomatika, 1960, No. 3, pp. 38-45
TEXTt This article gives a description of a designed low-power
servosystem with transistors workinC on a raised frequency with
an internal generator and transistors. The question is a single-
channeled scheme consistin6 of a modulator, an amplifier, a two-
phase asynchronous motor, a reducer, a potentiometer bridge and
of an RC-filter. The modulator (figure 2) is a reversible two-
stroke key-scheme witin, tile two transistors PI D with a low nois,.
level. At tile output Tr 1 the rectanoular impulses are sm,othed
by the condenser C 2'
An experimental study of the servosystem showed that the most
effective evaluation of the servosy,,,,tem, trued up to transient
responses with extremely little overcorrection is the servc error.
The servo errors of the system with transistors do riot exeed til~ose
of similar 9~stems v-.ith electronic tubeL within an am'U'ient tum~ert_-
ture range of + 60 0C to - 2~)0C.
