Kinetics of two-stage mechanochemical synthesis of calcium zirconate in CaCO3-ZrO2 system

Reaction of formation of calcium zirconate in CaCO 3 -ZrO 3 system at 1:1 molar ratio is studied at 800, 850, and 900°C. Preliminary mechanoactivation of the reagents mixture in the centrifugal planetary mill was used. Obtained conversion data were analyzed using a macrokinetic model of two-stage me...

Zusammenfassung:	Reaction of formation of calcium zirconate in CaCO 3 -ZrO 3 system at 1:1 molar ratio is studied at 800, 850, and 900°C. Preliminary mechanoactivation of the reagents mixture in the centrifugal planetary mill was used. Obtained conversion data were analyzed using a macrokinetic model of two-stage mechanochemical synthesis applying the Jander and Zhuravlev-Lesokhin-Tempelman equations.
