Reactive characterization of anhydrous iodine (v) oxide (I2O5) with aluminum: amorphous versus crystalline microstructures

The water–iodine oxide system: a revised mechanism for hydration and dehydration

“…Eqn (1)-(3) represent a model for the previously accepted hydration/dehydration mechanism that enables determination of the concentration of iodine species by TGA mass change measurements. A new model is presented in eqn (4)- (7). The major difference between the models shown is seen by comparing eqn (5) to (3) (4) assuming the initial concentration of HI 3 O 8 is 0%.…”

“…The major difference between the models shown is seen by comparing eqn (5) to (3) (4) assuming the initial concentration of HI 3 O 8 is 0%. The mechanism in eqn (4) is proposed because the accepted mechanism (eqn (1)) is a special condition but eqn (7) shows the conditions where the mechanism in eqn (4) is equivalent to the mechanism in eqn (1).…”

“…This sample is referred to as 17 mm I 2 O 5 because it has an average particle diameter of 16.9 mm. 7 The 17 mm I 2 O 5 is the same as commercial I 2 O 5 used in Smith et al 7 where characterization of these samples was performed. The second method is a "dry" method that combines elemental iodine and oxygen using a non-thermal plasma energy source to form spherical I 2 O 5 particles with an average diameter of 4.7 mm.…”

“…The second method is a "dry" method that combines elemental iodine and oxygen using a non-thermal plasma energy source to form spherical I 2 O 5 particles with an average diameter of 4.7 mm. 7 These samples were labeled nano C I 2 O 5 when used in Smith et al 7 because they were initially measured erroneously to have an average particle diameter of 400 nm. 7 This sample is now referred to as 5 mm I 2 O 5 here.…”

“…7 These samples were labeled nano C I 2 O 5 when used in Smith et al 7 because they were initially measured erroneously to have an average particle diameter of 400 nm. 7 This sample is now referred to as 5 mm I 2 O 5 here. The two distinct synthesis methods enable production of particles with discretely different properties inherent from the synthesis methods and tailored for experimental designs that focus on deriving a more general hydration/dehydration mechanism.…”
