KINETIC MECHANISM OF REACTION BETWEEN TT-PHASE NIOBIUM OXIDE AND CARBON TETRACHLORIDE (CCL4)

摘要

The kinetic mechanism of reaction between TT-phase niobium oxide and carbon tetrachloride (CCl4) at low (453 K) and high (above 573 K) temperatures was investigated. The reaction of the TT-phase niobium oxide with CCl4 at 453 K was controlled by the diffusion of CCl4 through the outer layer of the reaction product, NbOCl3, formed around the surface. For the reaction at temperatures above 573 K, the chemical reaction on the surface of the niobium oxide controls the total reaction rate due to the disappearance of the layer of NbOCl3.
