摘要

Abstract

Calcium sulfoaluminate

3CaO·3Al

·CaSO

has been widely recognized in the realms of high-temperature combustion and cement chemistry.However

the lack of relevant thermodynamic data limits the progress of its research and development.Through comparative calculations using several different approaches

we obtain the thermochemical properties of 3CaO·3Al

·CaSO

in this work

such as its standard formation enthalpy

Gibbs free energy of formation

entropy

and molar heat capacity.With these fundamental data

thermodynamic calculations become possible for reactions involving this mineral.It is found that some reactions proposed in literature to generate this mineral may not proceed thermodynamically.
