Abstract

The potential use of a mathematical simulation method for accumulative recrystallization of magnesite of provenance from the Chita deposit is considered. The densification rate in sintered MgO, that is, the rate at which grain boundaries form at the expense of contracting intergranular pores, is shown to be much higher than the rate at which the grain boundaries disappear during the accumulative crystallization. An equation is derived that provides an adequate description of the kinetic features of MgO sintering. The numerical parameters of this are physically meaningful, which allows one to gain deeper insight into the sintering mechanism of MgO and thus go beyond the limits of a purely phenomenological approach.
