ABSTRACT: Independent studies of the system CaB04 - M9304 - H20
were made using for the determination of calcium the
alcohol method and the tracer (Ca45) method. Measure-
ments were also made of the viscosity and specific
gravity of various solutions of the system. With the
aid of the traner method it was shown that the true
solubility of calcium sulphate in the system is less
than the solubility found by using the alcohol method,
which is probably due to coprecipitation of magnesium
with the calcium in the latter. With either method,

ABSTRACT: Experiments for the explanation of the process of
formation of primary polybalite . viere carried out at
350C by the evaporation of ujnthetic solutions by ad=
ding acqueous calcium sulfate solutions.
The chemical analysis of the obtained deposit showed
that more than 95% of the deposit consistsof purest
polyhalite - K SO LISSO 2 CaSO FT,O
2 4 4 4
The microscopical investigations confirm this result.
It results from the thermographic curve that a complete
dehydration of polyhalite occurs at 32ooC and that
melting begins at 88o0C.
The formation of primary po4hallte -ias confirmed by
the chemical, crystallo-optical and thermographical
Card 1/2 analysis.

ABSTRACT: An investigation was carried out at 35 0C of the solubility
of the salts, the viscosity and specific weight of solutions
of the system K2 so 4-ugso 4-CASO 4-H2O,as well as of the
ternary systems K 2so 4_MgSO 4-H20 'K2 SO 4_CsSO 4-H20 and
Caso 4_Mg30 4H 20 belonging to this system. In the investiga-
tion of the four-component system the following salts were

in the system analyzed at 35 00 only in the range of higher
concentration of magnesium sulfate. The crystallization
range of pollygallite is extended considerably when
temperature is increased. In the solid phase of the system
polygallite is at 35 0C in paragenesis with gypsum,singenite,
schenite and epsomite. In the potassium deposits of the
Volga-Emb and the Carpathians , polygallite is in paragenesis
with the following sulfates: anhydrite -,(Caso )-, gypsum,
kieserite-(MgsoV H 20)-, langbeinite -(K 2 SO4. 4 2MgSO 4)_
and glaserite -( 3 K 2soV Na 2s04). The results of the
solubility of the ternary systems correspond to those
obtained from the investigations of viscosity and specific
weight of the systems. The results of the physicochamical
analysis of the four-component system K 30 4-MgSO -CaSO -
H 0 are of i portance for the explanation of thi formition
of natural pomlygallite. The formation of polygallite in
nature,which is caused by evaporition of sea water, takes
