Peculiarities of Serpentine Decomposition in the Presence of Alkaline Chloride: Raman Study at High Pressure and Temperature

In situ Raman spectroscopy combined with a resistively heated diamond anvil cell was used to study the behavior of serpentine (chrysotile) Mg 3 Si 2 O 5 (OH) 4 in the presence of NaCl at 100–400°С and 10 kbar. Low H 2 O activity leads to a decrease in the dehydration temperature by about 200°C compa...

Description
Summary:In situ Raman spectroscopy combined with a resistively heated diamond anvil cell was used to study the behavior of serpentine (chrysotile) Mg 3 Si 2 O 5 (OH) 4 in the presence of NaCl at 100–400°С and 10 kbar. Low H 2 O activity leads to a decrease in the dehydration temperature by about 200°C compared to a salt-free system, as well as the formation of only anhydrous products.
