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 determ

This paper examines the effect of mechanical activation by impact and attrition milling in planetary and ball ring mills on the phase composition of gypsum. Partially dehydrated powders obtained without heat treatment contain up to 60–70% β-CaSO4

Thermal transformations of a commercial aluminoborophosphate binder are studied in a broad temperature range by optical microscopy, x-ray diffraction, IR spectroscopy, and thermal analysis. The introduction of B2O3 reduces the temperature of phosphat

The influence of various pretreatments (predominantly impact and attrition in a planetary activator and a ball ring mill, respectively) preceding the formation of periclase on the mechanical properties of raw and sintered samples is studied. The defo

The amount of associated carbon dioxide is found to depend on the technique of CaO pretreatment. Distended imperfect surface layers of the oxide prepared in a jar mill are more reactive in comparison with the oxide that was not subjected to any mecha

We have studied the kinetics of molybdenum trioxide desorption from the alumina surface after mechanical activation of Al2O3 + MoO3 mixtures. Mechanical activation has been shown to considerably inhibit MoO3 thermal desorption. The apparent rate cons

The incorporation of phosphoric anhydride into α- and γ-aluminas during mechanical activation is investigated. An empirical equation is proposed for the kinetics of P2O5 incorporation. The effect of the specific power of the mill on the amount of b
