Abstract
The kinetic mechanism of reaction between TT-phase niobium oxide and c arbon tetrachloride (CCl4) at low (453 K) and high (above 573 K) tempe ratures was investigated. The reaction of the TT-phase niobium oxide w ith 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 d ue to the disappearance of the layer of NbOCl3.
