Abstract

Abstract: In situ Raman spectroscopy combined with a resistively heated diamond anvil cell was used to study the behavior of serpentine (chrysotile) Mg3Si2O5(OH)4 in the presence of NaCl at 100–400°С and 10 kbar. Low H2O 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.
