Popis:	The sintering kinetics of periclase with brucite-aluminum phosphate binder was studied. A model that takes into account the role of the physical compaction and chemical binding in the presence of a binder during the heating process was used to determine the kinetic parameters. The strength of a conglomerate was due to the sintering itself as well as the action of the binder. The effective energy of activation of the sintering of periclase was determined: Ea = 287 ± 9 kJ/mole, which is close to the activation energy of oxygen diffusion in MgO. Spinel MgAl2O4, which slows the sintering process, forms in the material at high temperatures.
