Abstract

Thermal decomposition of smithsonite has been studied by thermogravimetry and differential thermal analysis. X-ray diffraction was used to characterize smithsonite and its product of decomposition, zincite. The activation energy value is evaluated with TG and DTA methods. The order of reaction and pre-exponential factor in the Arrhenius equation are determined also.
