The thermal decomposition of certain metal chromates(VI)

100%

Pisarska-Piesse B. B. , Gontarz Z.

tom Vol. 72, nr 9

2067-2078

The thermal decomposition of M(I)2CrO4 (where M(I) = Li, Na, K, Rb, Cs, Ag, Tl), M(II)CrO4 (where M(II) = Mg, Ca, Sr, Ba), M(III)2(CrO4)3 (where M(III) = La, Nd) has been investigated. Mechanisms of invidual stages of the thermal decomposition have been proposed on the basis of morphological classification. The effect of cationic counterions on the decomposition of chromates (VI) is described.

Thermal Reactions of Some Calcium, Strontium and Barium Chromates

80%

Pisarska-Piesse B. , Gontarz Z. , Ostrowski A. , Kucharski R.

2000

tom Vol. 74, nr 10

1479-1479

Thermal decomposition of calcium chromates and solid state reactions of barium and strontium chromates(VI) with barium and strontium hydroxides and carbonates, as well as the reduction of chromates by carbon and hydrogen, have been investigated. The mechanisms of individual stages of the thermal decomposition have been proposed on the basis of the morphological classification.
