Abstract

The mineral lawsonite, CaAl2Si2O7(OH)2⋅H2O, was deuterated to about 93% in a thermobalance by H2O-D2O gas-phase exchange at temperatures between 375 and 425 °C. The kinetics of this reaction are reported and diffusion coefficients for the H2O-D2O exchange are calculated from thermogravimetric measurements.
