TrrLE: Photoelectric characteristics of a two-terminal p-n-p-n type transistor switch

ABSTRACT: The article deals with the method of fabrication and photoelectric characteristics
of germanium-base p-n-p-n type transistor switches. The starting material was a p-type
wafer with a resistivity of 5 ohms- cm and dimensions of 1. 3xi. M. 08 mm. Twop-njunctions
ivere obtained by diffusing antimony into both surfaces of the original wafer and the third, by
alloying indium into one of the diffused layers. Ohmic contact on the opposite side was accom-
plished by doping with tin (Fig. 1). In the presence of a fixed bias lower than the svdtching

type switch:

voltage the device is in the "off" state (point A on V-I characteristic in Fig. 2) and displays a
high resistance of the order of several megohms. On illumination the switch changes from
"off" state to "on" state (point B in Fig. 21) considering that the fixed bias voltage is then .
sufficient for breakdown of the center p-n junction. In this position the resistance of the de-
vice is of the order of several ohms. An investigation of V-1 characteristics in the presence of
darkness and various degrees of illumination conclusively proved that switching voltage de-
creases with increasing illumination. The minimum illumination required to switch the de-
vice is of the order of 100-150 lux. Further improvements in the design and fabrication of
transIstor switches should make it possible to develop more photosensitive and stable devices

PERroDiCAL: Kemija u industriji, 1959, Nr 1, pp 21 - 26
ABSTRAM The author emphasizes the need for more extensive Use of
fertilizers and increase in their production and j.-,ive.3 a
description of the chemical composition, import and the
present and planned production of various fertili%ers.
1. Nitrate fertilizers: a) calcium cyanarjide is produced
by the plant in Dugi Rat and the Tvornica dugika (Nitrogen
Plant) in Ru'se. Their total production capacity is 44,000
tons, but their actual production is only 50 of their ca-
pacity. With the construction of' the new plant in Jegunovei
this capacity will be increased by 33,000 tons, and should
meet the requirements for this kind of fertilize.-i b) am-
monium sulfate is mainly produced as a component for mixed
fertilizers by the Koksara (Coke Plant) "Boris Ki,ir&l and
the coke plant in Zenica. The total yearly production of
these two plants is 9 - 10,000 tons; c) ammonium nitrate
Card 114 of which the Fabrika azotnih jedinjenja (Nitrogen Compounds

lugoslavis
V
Plant) in Gorazde, with a yearly capacity of 24,000 tons,
is the only producer. About 5 - 6,000 tons of the total
yearly production is used for production of mixed fertili-
zers and the rest is divided between export and the supplies
for the chemical industry. 2) Phosphate fertilizeirsi
a) superphosphate is produced bj "Zorka" in Subotioa, "Cin-
karna" in Celje and "Zorkall in abac. Total capacity is
260,000 tons yearly, and expansion of these Plants is plan-
ned; b) hyperphosphate, the production of which started in
V
1957 by the "Tovarna dugika" (Nitrogen Plant) in Ruse, is
obtained by grinding imported crude phosphate. Yew plants
should be constructed in the vicinity of the Adriatic ports
to save the cost of double transport, since the Adriatic
coastal area is the main consumer of this fertilizer.
3) Mixed fertilizers, i.e. "amonfos", "nitrofos", "nitrofos-
kal" and "RAS", are produced by "Zorka" in Subotica slid
IlTovarna duiika" (Nitrogen Plant) in ~absc. The :raw mater-
~'Iard 2/4 ials required for the production of these fertili,.,ers are

Yr,'J/2-59-1-16/22
Production of Artificial Fertilizers in the Federal People's Republic of
Yugoslavia
imported, since the domestic resources are negligible. The
total production of all three kinds of fertilizers, i.e.
nitrate, phosphate and mixed, dcas riot satisfy the need
and individual mixed-fertilizer mixing stations are to be
built in consumer centers. Since the new plants which are
planned to be constructed by 1961 will not be completed by
that date owing to the consistent refusal of the USSR to
give the necessary loans, agriculture will still depend on
imported fertilizers or on the import of raw materials for
production of fertilizers. The import of potash fertiliz-
ere is a permanent feature of the Yugoslav economy since
there are no adequate domestic sources of raw material for
these fertilizers. The author emphasizes the need for plan-
ning for the period after 1961, for construction of phos-
phate fertilizer plants in the Western regions Of YUg03la-
via, and for the production of concentrated fertilizers,
i.e. tricaloium phosphate and ammonium phosphate. The
Card 3/4 shortage of nitrate fertilizers could b; overcome with the

YUG/2-59-1-16,/22
Production of Artificial Fertilizers in the Federal People's RepublIc of
Yugoslavia
domestic sources of bonded nitrogen, i.e. natural gas and
lignite. Crude phosphorus will still have to be imported
and phosphoric acid required for various kinds of fertili~--
zers could be produced by thermal process in locations with
a seasonal surplus of hydropower. There are '7 tables and
10 references, I of which is French and 9 Yugoslav.

TITLE: Solid state reactions between metal heaters and ceramics

PERIODICAL. Tehnika, no. 5, 1960, 971-972
TEXT: The authors outlined the reactions and mechanism& of Mo with the
AL 203- SiO 2 system, and a Cr-Fe - Al alloy with the systems AL 203

(0.3 --0.6 mm bead size) Sipalox A and Sipalox C (60% Al 2o7 anej 70%
AL203 respectively) materialso and then heated to an optimum tempera-
ture of 1.300OCo Investigations showed that corundum powder in place of
Sipalex Rand C does not react with the wires at all* Reaction in the
case of the alley and Al203 in attr1buted to the presence of quartz in
the Sipalox material. The mechanism is postulated as follows: on
heating Al diffuses to the surface of the alloy where it oxid.-Izes,
forming an impermeable layer preventing further Al diffusion; but,
with free quartz present, the oxide cost reacts with SiO 2; aluminum
continues to diffuse to the surface, where it reacts with SO 2 . The
diffusion coefficient of Al in iron is greater than the diffus on
coefficient of ehromium in iron, which supports this theoryo Deter-
mination of the Al contents of the alloy on heating with the ceramics

also support this mechanisms The more rapid loss of Al and lower re-
action time in thinner wires is due to a much smaller volume/area
ratio, as compared to thicker wires. When the A! in the alloy is used
up and can no longer form a surface layer, reaction between quartz and
C:r and Fe oxides proceeds quickly. This mechanism also applies to
Hgo-Sio2 type ceramics whore free MgO can react with coats of Al 203
to build spinels. (11) The reaction between Al 203 - Sio 2 and Mo is
due to the presence of free quartz in the ceramic mulls, together with
the increased electrical conductivity of mulls above 1000 C. Short
circuits thus arise the molybdenum spirals, melting the refractory
former and thus giging rise to reactions. Quartz reacts with molybdenum
oxide even at 1320 C, and to stop this, MgO has been added to remove
free quartz. The pure Al 0 carrier, "SintereorUnd" is more efficient;
it. was found unreactive ai i former even at 1950 C. (III) Reactions of
111203with Mo, W, and Pt. In high vacua A1.03 and Mo do not react9
nor do they do so in pure H 2, but if the hydrogen contains traces of

oxygen gray spots appear at the contacts; those spots increase with
an increase in contamination, showing reaction. The eleatrical pro-
perties of tungsten were measured in high vacuum at 1500 C, when it
showed no reaction with alumina. Platinum does not react, but in re-
ducing atmospheres, minute amounts of quartz present transform to
SiO, which reacts with Pt given platinisilicides, important in therme--
couples of the PT/PT-Rh type. (IV) Reaction of C, W, Mo with ZrO 2 and
HgO.. Ceramics of the ZrO2 and MgO type react with C, W, and Mo at high
temperatures at pressures of 10-4 _ 10-5 Torr. In fact all these materials
-eact with each other at high temperatures and in intimate contact. In
tonclusiong a Cr- Fe - Al alloy reacts with A120, - Si02 and MgO - SiO2
type ceramic carriers only if free0quartz in present* Mo if oxidized
at the surface reacts even at 1300 C with quartzj to form molybdenum
silicatoq. Hence the following systems can be used for construction of
furnace heating elements: (1) Fe - Cr - Al alloy and ceramics free from
quartz and MgO. (2).Me heaters and sintered corundum (pure A12 03)S
