Abstract
A flue for cooling the flow of reaction product from the high temperature oxidation of a metal halide to the metal oxide in the presence of oxygen, said flue comprising a first section wherein the cross-sectional area is increased thereby decreasing the turbulence of the flow and a second section wherein the cross-sectional area is decreased thereby increasing the velocity or turbulence of the flow and the process for using said flue to produce an agglomerate of TiO.sub.2 particles that are readily filterable and easily ground.
