ABSTRACT: The changes introduced into the apparatus for drop- tempornetric
potentiometry (Kalye A. K. , Zavodsk. laboratoriya, 1946, v6i 12, r4r 9)
are pointed out. The titration of 0. OIN solution of (CH3COO)2Pb
with 0. IN solution of K Cr04'of 0. 01N solution of AI(NO3)3 and
0. MIN solution of Fe(~83)3 with 0. IN solution of NaOH was
carried out. In determining 15 - 52 mg Pb the error constitutes
0. 78 - 1. 95 mg Pb; in determining 1. 34 - 4. 5 mg Al, the error
equals 0 - 0. 14 mg Al, and in determining 0. 19 - 0. 93 mg Fe
accurate results are obtained. The observed lag in the increase
of time necessary for the titration, owing to the increase of the
amount of the ion titratec~ is explained by the increase in the co-

TITLE: Investigation of~e Tempe~rature Dependence of the Work
Function of Metals (Issledovaniye temperaturnoy zavisi-

PERIODICAL: Radiotekhnika i Elektronika, 1958, Vol 3, Nr 8~
pp 1000,- 1004 (USSR)
ABSTRACT: A description of the method of measurement of the work
function is given and some experimental results are
reported. The method was first proposed by Lukirskiy
(Refs 2, 3 and 4). The method permits the measurement
of the contact potential diffe:-ence of two substances,
i.e. the difference between th-iir work functions. Since,
in this work I the aim was not -zhe determination of the
absolute value o f the work function but its variation,
the method was particularly suitable for the measurements.
The experiments were carried out by means of a special
tube ~Figure 1) which consisted of an electron gun of the
blyers type (Ref 6) and of a tarSet in the form of a
hollow cylinder. The electron j~un was furnished with
a fine focusing arrangement which was situated at a
Gardl/4 distance of about 2 cm from the target. The target

(Figure 2) was made of metal plate having a thickness
of 0.1 mm and was fitted with a heater; this arrangement
ensured the equipotentiality of the target surface. The
heater of the target was made of a double-helix, tungsten
wire, so as to reduce the maGnetic field due to the
heater current. The heater was used not only for raising
the temperature of the target but also for the de-gassing
of the system. The internal walls of the experimelital
tube were coated with a conductinC layer which was Given
a potential of the last anode (FiBure 1). The metal parts
of the tube were thoroughly de-gassed and, after sealing
off the pressure inside the tube was reduced to about
mwHg by means of two ionisation-type pumps. The
measurements vere carried out in the circuit shown in
Figure 3- Since the measurements had to be made at a
constant teWperature within a tempTature range of
20 - 1 000 C, the temperature of the cathode was con-
trolled by measuring its resistance by means of the
Thomson bridge. The current at the target was measured

by means of a galvanometer having a sensitivity of
4 x.10-11 A/division. The measurement of the contact
-potential difference was as follows: the current-voltage
characteristics were plotted on a semi-logarithmic scale;
in the region of small currents, the graphs could be
approximated by straight lines. Also, for each temperature
a current curve was determined and its intersection with
the straight line was found. From this, it was possible
to determine the contact potential difference. The
error of measuremgnt of the contact potential difference
was about 5 x 10-` V. The experimental-results are shown
in Figure 4, which represents the work function for a
molybdenurn tax-get. The 'dashed' curve in Figure 4
represents the direct results of the measurements, while
the full curve represents the values of the work function
after correction; the corrections were evaluated by
taking into account the variation of the electrochemical
potential of the system. The results represented by
Figure 4 should be regarded as preliminary and it is

Abstract An experimental investigation was made of the electron
emiSsion of polycrystalline molybdenum at tempezatures
700 -- 1100' K. This investigation has made it possible
to establish that the temperature coefficient of the work
function equals in this case (7-86 t m4) x lo-5 ev/deg.
It is noted that the measurement accuracy obtained in
this work is two orders of magnitude higher than in prece-
ding investigations by other authors.

TEXT: The experimental ionization glass pump designed by the Inatitut
atomnoy fiziki (Institute of Atomic Physics) '(Buiaharent) evacuates air 'down to
7.10-9 mm Hg. After preliminary evacuation, the valv6 connecting the evacuated
container with the forevacuum, is shut off, and 2.5 kv voltage is supplied be-
tween the tungsten filament and the titanium wire grid in the ionization PUMP
The titanium is brought to incandescence by bombardment with electrons emitt7e;
by the'.tungsten; it evaporates and is precipitated onto the pump walls,, forming
a 0.1 - 0.2 'u layer of about 150 CM2 surface wl~hin 30 minutes. The pressure in
the pump As meanwhile maintained as high as 10 mm Hg. Then the voltage sup-

Investigation of an ionization pump with... A006/A101
has practically a cathode potential, and inside the pump conditions are created
which promote ionization or excitation of gas molecules. The titanium absorbs
ionized or excited molecules, in particular those of nitrogen and water. Under
these conditions the evacuation rate attains 5 liters/see. Evacuation is com-
pleted within 2 hours of the ionization pump operation, at 4 hours preliminary
evacuation. With the aid of a diffusion pump the same results are obtained after
80 - 100 hours operation. General information Is given on the operation of imi-
z&tion pumps; a description is given of a unit for testing the aforementioned V~
pump; some results of tests are presented showing conform evacuation rate plues
obtained by both methods, and absorbability of titanium was deiermined (10- mm
Hg'liter/mg).

obtained by themselves and other authors it is shown that while
the pressure is decreasing, particularly during long pumping t mesif

and'also during recovery, a decisive role is played by desorption,'
from the wall,s of molecules which were absorbed independently of
pumping. It',is shown that whon.there aro,chhnges of pressureAn
