An alumina tube (30 mm internal
diameter and 1 m long) placed horizontally in a high temperature
furnace
Thermal Gradient Tube up to 2.5 m lenght - Max temperature of 1600°C down to 150°C
To determine chemical speciation, deposits and transported species at low T (containment) - aerosol and gas measurements
Pressure between 1 and 2 bars, temperature gradient between 1600 and 150°C, mass of gaseous iodine, residence time, composition of the carrier gas (H2O/H2/Ar), nature and concentration of injected elements in the line.
