摘要：
The kinetic method is suggested to estimate a ratio of share of the solid- and liquid-phase contacts in the heterogeneous dispersed materials. It is based on comparison of process rates of solid-phase sintering with formation of contacts and phase dissolution in melt. The method enables to predict a variation of relative position of phases depending on the properties of contacting crystals in liquid. The sintering experimental data are presented for iron ore concentrates roasted at temperature higher than 1300°C.
