THERMAL-DECOMPOSITION OF ANALYTICALLY IMPORTANT THIOCYANATOCHROMATES(III) .1.

Thermoanalytical studies carried out on complex salts Ag3[Cr(SCN)6], Tl3[Cr(SCN)6] and Hg3[Cr(SCN)6]2. On the basis of thermal analysis, and X-ray and chemical analyses of their decomposition products, schematic representations of the thermal decomposition reactions were established. From thermogravimetric curves, kinetic parameters were calculated using the methods of Coats-Redfern and Zsako. A comparison of the thermal stabilities of the compounds was made.
