(Izuehenive rastvorimosti sistemy GaS04 - M9304 - H20 pri 350 metodom mechenykh atomov.) PERIODICAL: Zhurnal Neorganicheakoy Xhimii, 1957, Vol.II, Nr.3, pp. 662-668. (USSR) 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, Card 1/2 the solubility curve at 356G. showed a minimum and a NOVIKOl/4L'#L'."V.q(;nnd Chem "Sci-((Uss) "Study of salt cquilibr-An in the !f2SO,I-l!tE;()4-CvSO4-'120 sy""m rtt 35",nnd 44o obttining of AWW prirv.~%ry polyhalitc." h~oo, 195-5. 13 pp (Acad Sci USSR.

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.

In the investiga- tion of the four-component system the following salts were ascertaineds polygallite -(K. so 4* MgSO 4* 2CaSO 4* 2H 20)-' singenite -(K2so 4' Caso 4_H2O)_' gvpsum-(CaS04' 2H 20)-' K2 so 4* 5CaSO 4*H20, schenite- (K2so 4' mgSO 4* 6H 20 )-, epsomite - Card 1/3 ugso 4' 7H2 0 ) and arcanite( K 2'304), Polygallite is formed PhysicochIemical Investigation of the K2so 4_*SO 4- SOV/78-3-10-27/3115 ;Ca So -H OjSystem at 350 4 2 1 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.
