Abstract
The decomposition characteristics of four magnesium oxychloride
phases in the system Mg0-MgCI2-H20 were studied by the thermogravimetric
method. The decomposition rate curves obtained at
different temperatures in the interval 100°-SOOoC were found to
follow formal first order kinetics. The activation energy values
of the decomposition reactions were calculated to compare the
thermal stabilities of the phases. The 5-phase was suggested as the
desirable one in magnesium oxychloride cement for high temperature
application as refractory castables.
