Rheological transition and mechanical properties of alumina–agar mixtures under temperature cycling

Abstract

This study examined the gel formation behavior and temperature-dependent mechanical characteristics of gel-cast alumina-agar mixtures. The shift from viscoelastic to elastic behaviors, the influence of final agar content, the reversibility of the viscoelastic-elastic transition, and the relationship between complex modulus and temperature were all investigated. The complex viscosity of the mixtures was also investigated to determine their role in ceramic shaping operations. The findings are useful for academics and practitioners in materials science and engineering, especially those who work with alumina-agar mixtures.
