PERIODICAL: Ogneupory, 1958, 0 , Nr 4, PP. 163-168 (USSR)
ABSTRACT: Tests with Forsterite products in a copper smelting furnace were
carried out in the USSR for the first time. They were bricked up
in the vaults of the charge openings of the furnace ana operatea
at temperatures of 1300-14000. As a result of the action of tem-
perature and smelt dust Forsterite assumed a zonal structure which
is further described. The chemical composition of the worked-off
Forsterite products according to zones as well as other data were
published in papers -by I.P. Bas I yas 'M.M. Dvorkind, I.G. Sarkisov
and P.F. Postnikov (Ref 1). Fig. 1 shows the structure of the un-
changed part of a Forsterite brick and fig. 2 shows its dark-grey
zone. Fig, 3 shows the structure of the dark-grey and "spinel-

seen, it is considerably swollen. The influence exercisea by gas-

Forsterite brick whi--h wa-9 heateJ in an 302 current. Table 2
gives the results obtained when determining SO - Mg-, and Fe-
quantities. Conclusions: 1.) Reagents of the srel'ting space in in-
teraction with Forateri-re bricks form a "spinel-like" zone.
2.) In the middle of the remaining l1ength of Forsterite products,

milieu upon refractory forsterite products was investigated.

described how these experiments -.,ere carried out. Table I
shows the results obtained after modification of the proper-
ties of the sample after treatment both in an oxidizing and
in a reducin- -as milieu, which are mentioned and described.
Moreover, the influence exercised by the Eas :ailieu upon syn-
thetic samples of dunite found at Uktussk with an addition of
metallurgical magnesite, technical alumina, and quartzite
found at Pervourallsk was invectigated, The test results are

Conclusions: 1) in a laboratory plant the influence exercised
by the oxidation and regeneration ;,-ii-lieu upon the loosening
of refractory forsterite products was investigated 2) It was
found that the regeneration milieu causes loosening of the
forsterite products, which is manifested by the increase of
the volame and by the p=.-.cability to gas. 3) Loosening is
caused by damage done to t~-_ stricture of the products-

TITLE: On the Summ. x.tional Refractive Index of Refractory Chamotte
Products and the Separation of Their Glass-like and
Crystalline Phases on Burning
FERIODICALt Ogneupory, 1960, Nr 1, PP 33 - 34 (USSR)
ABSTRACTt In this paper, the authors state that the summ a tional re-
fractive index of chamottes increases with the rise of the
+e erature of burning to a certain temperature only which
Zds on the type of raw material and buining duration. On
burning the clay at a higher temperature, the sum malional
/
refractive index of the chamottes decreases. Concrete data V
on this dependence are'given in the papers by E. K. Keler
and Z. I. Veselova (Ref 2). Repeated burning of chamotte
'tional refractive index (see
products decreases their sumjjsa

background in haystacks from pastures from various-highland areas.
Gamma spectroscopic and radlochemical studies have been made of soili,
and other samples to explain the origin.of the anomalies observed. I
Analysis of the data of field and laboratory investigations indi
cates the presence of a new phenomenon, namely a local accumulation
Of fission products due to global contamination as the result of
current nuclear tests. Some of the concentrations of fission prod-
ucts found in the soil are very high.and give grounds to assume the.
.presence of active factors of transfer and migration of fission
products from tho atmosphere to the ground. The approximate age of
the mixtures of radioisotopes has been determined,and the ratio of
the basic long lived products cerium-144 and cessium-137 has been
determined. The investLgation,is still in its initial stage, how-
ever, it has been established beyond any doubt that radioactive fall
out, concentrating under the action of meteorological, hydrological.,
-orographical and other factors, may create a viry high level of.locat
radioactive contamination even under the conditions of global dis-
persal of long lived products originating fron the stratosphora
