INFLUENCE OF MORPHOLOGY, PHASE COMPOSITION AND CONTENT OF ALUMINUM OXIDE PARTICLES ON RHEOLOGICAL PROPERTIES OF AQUEOUS SUSPENSIONS BASED ON THEM

This work investigated the chemical and phase composition of aluminum oxide powders obtained by various methods (alkoxide, codeposition, thermal and plasma-chemical). The physicomechanical, thermophysical and thermal properties of ceramic samples based on them have been determined. The effect of the nature of the aluminum oxide powder and the production process parameters on the sedimentation stability of aqueous suspensions based on them has been determined. The influence of the content of particles of aluminum oxide, buffer solution and rheological additives on the viscosity, sedimentation and aggregate stability of aqueous suspensions has been determined.
