Abstract
Thermal decomposition of Cr(NO3)(3).9H(2)O in helium and in synthetic air was studied by means of TG, DTA, EGA and XRD analysis. The dehydration occurs together with decomposition of nitrate(V) groups. Eight distinct stages of reaction were found. Intermediate products of decomposition are hydroxy- and oxynitrates containing chromium in hexa- and trivalent states. The process carried out in helium leads to (Cr-0.07Cr-0.93O-2.90)-Cr-III-O-VI at about 260degreesC and in air (Cr-0.01Cr-0.99O-2.99)-Cr-III-O-VI is formed at about 200degreesC. The final product of decomposition (>450degreesC) is Cr2O3, both in helium and in air.
