摘要: Abstract The rheological and chemorheological properties of aqueous γ-LiAlO 2 slurries for gel-casting as well their precursor solutions methacrylamide N,N′-methylenebisacrylamide (MAM/MBAM) were studied in the present work. influences mean particle size powder, dispersant content solid loading, mechanical stirring time on rheology investigated systematically. It was demonstrated that exhibited shear-thinning behaviors with relatively low viscosity which could satisfy process. A rotary rheometer used to study chemorheology copolymerization MAM/MBAM solution gelation process slurries. activation energy calculated from idle 27.5 ± 0.4 kJ/mol 25.3 ± 0.4 kJ/mol, respectively, revealed catalytic effect particles
